                    General Instructions

                    In this activity, you will link the types of intermolecular forces possible between atoms or molecules in condensed phases (dispersion forces, dipole-dipole attractions, and hydrogen bonding), correlate the types of intermolecular forces experienced by specific molecules with their structures, explain the relationship between the intermolecular forces present within a substance and the temperatures associated with changes in its physical state, and identify and contrast inter and intramolecular forces. To successfully achieve this, you will need to review module five's study materials (bonding and chemical interactions).

                    Step 1: Select and Reflect

                    Read the topic below and demonstrate your understanding of intermolecular forces in theoretical and practical settings.

                    • Intermolecular forces

                    Step 2: Respond

                    Using supporting data for your arguments, prepare a 300-350 words written piece that answers any of the following questions based on the scenario you selected. 

                    Case Scenario 1: 

                    The chemistry lab has two students tasked with understanding the different types of intermolecular forces possible between atoms and molecules in dispersed phases. The first student studies two gases, hydrogen and oxygen, and their interaction in a dispersed phase. The student observes the two gases undergoing hydrogen bonding. 

                    The second student studies two liquids, water and ethanol, and their interaction in a dispersed phase. The student observes the two liquids undergoing hydrophobic interactions and hydrogen bonding. 

                    Questions:

                    1. Describe the strongest type of intermolecular force that occurs between two molecules containing hydrogen atoms and other atoms, like oxygen.
                    2. Describe the interactions and bonding taking place as observed by the second student.

                    Case Scenario 2: 

                    You are a chemist in a laboratory tasked with determining the intermolecular forces experienced by two specific molecules: ethanol (C2H6O) and propane (C3H8). 

                    Questions: 

                    1. What type of intermolecular force is present in ethanol? 
                    2. What type of intermolecular force is present in propane? 
                    3. How does the structure of ethanol contribute to the intermolecular forces present? 
                    4. How does the structure of propane contribute to the intermolecular forces present? 
                    5. How would the intermolecular forces be affected if the temperature of the molecules was increased?

                    Case Scenario 3:

                    The intermolecular forces present in a substance can greatly influence the temperatures at which it changes its physical state. For example, when a substance with strong intermolecular forces is heated, it will require a higher temperature to transition from a solid to a liquid or from a liquid to a gas. On the other hand, a substance with weaker intermolecular forces will require less energy to transition between different physical states.

                    Questions:

                    1. What factors impact the strength of intermolecular forces in a substance?
                    2. How do intermolecular forces affect a substance's boiling and melting points?
                    3. What happens to intermolecular forces when a substance transitions from one physical state to another?
                    4. How does the strength of intermolecular forces influence the ease of changing a substance’s physical state?

                    Step 3: Share

                        General Instructions

                        In this activity, you will read expository essays and explain the function of a catalyst in terms of reaction mechanisms and potential energy diagrams, list examples of catalysis in natural and industrial processes, and compare the functions of homogeneous and heterogeneous catalysts. You will also write a balanced chemical equation for a process given its reaction mechanism. To successfully achieve this, you will need to review all the study materials for module five on bonding and chemical interactions.

                        Step 1: Select and Reflect

                        Read the topic below and demonstrate your understanding of intermolecular forces in theoretical and practical settings.

                        • Intermolecular forces

                        Step 2: Respond

                        Using supporting data for your arguments, prepare a 300-350 word written piece that answers any of the following questions based on the scenario you selected. 

                        Case Scenario 1:

                        A catalyst is used to increase the rate of a chemical reaction. It does this by providing an alternative pathway for the reaction to take place with lower activation energy. In this experiment, two different catalysts are tested in the reaction of 2 molecules of A to form 1 molecule of B and 1 molecule of C. Catalyst 1 is a homogeneous catalyst, while catalyst 2 is a heterogeneous catalyst.

                        Experimental Numbers:

                        Catalyst 1:

                        Activation Energy: 10 kcal/mol

                        Reaction Rate: 0.2 mol/min

                        Catalyst 2:

                        Activation Energy: 7 kcal/mol

                        Reaction Rate: 0.3 mol/min

                        Questions:

                        1. How does the use of a catalyst affect the rate of a chemical reaction?
                        2. What is the difference between a homogeneous and heterogeneous catalyst?
                        3. How does the activation energy of a reaction influence the rate of the reaction?
                        4. How does the reaction rate of catalyst 1 compare to that of catalyst 2?
                        5. What factors might explain the difference in reaction rates between the two catalysts?

                        Case Scenario 2: 

                        Catalysis is an essential process in both natural and industrial processes. In nature, catalysts are used to speed up chemical reactions, allowing them to occur more quickly and efficiently. For example, enzymes such as cytochrome c are used in biological processes, such as the breakdown of glucose molecules into energy. In industry, catalysts are used to increase the efficiency and control of chemical reactions, resulting in products with fewer environmental impacts and lower costs. Catalysts are used to produce a wide variety of products, including fuels, drugs, detergents, plastics, and fertilizers.

                        Questions:

                        1. What are some natural processes that use catalysis?
                        2. How does using catalysts in industrial processes increase efficiency and reduce environmental impacts?
                        3. What types of products are produced by using catalysts in industrial processes?
                        4. How does the use of catalysts in industrial processes reduce costs?
                        5. What role does cytochrome c play in biological processes?

                        Case Scenario 3:

                        A chemist is conducting an experiment to compare the functions of homogeneous and heterogeneous catalysts. The chemist sets up two identical experiments, one with a homogeneous catalyst and one with a heterogeneous catalyst. In each reaction, the chemist adds the same amount of reactants and the same amount of catalyst. The chemist then measures the rate of reaction in both experiments and observes the differences between the two catalysts.

                        Questions:

                        1. What are the differences between homogeneous and heterogeneous catalysts?
                        2. How does the rate of reaction differ between the two catalysts?
                        3. What factors might affect the effectiveness of each catalyst?
                        4. What are the possible implications of using one type of catalyst over the other?
                        5. How could the experiment be improved to provide more accurate data?

                        Case Scenario 4:

                        A student is studying the reaction mechanism of a chemical reaction between two compounds, A and B. Compound A is a molecule with three carbon atoms and four oxygen atoms, while compound B is a molecule with four carbon atoms and three oxygen atoms. The student wants to determine the reaction rate between the two compounds and the products of the reaction.

                        To do this, the student first draws the Lewis structure of each compound. The Lewis structure of compound A shows two double bonds and two single bonds between the carbon and oxygen atoms. The Lewis structure of compound B shows three double bonds and one single bond between the carbon and oxygen atoms.

                        Next, the student draws a reaction mechanism diagram to illustrate the steps that occur in the reaction. According to this diagram, when compound A reacts with compound B, an intermediate compound C is formed. This intermediate compound C has two double bonds and two single bonds between the carbon and oxygen atoms.

                        The student then uses the reaction mechanism diagram to write a balanced chemical equation for the reaction. The equation shows that two molecules of compound A react with one molecule of compound B to form one molecule of intermediate compound C, and two molecules of product D.

                        Questions:

                        1. What is the Lewis structure of compound A?
                        2. What is the Lewis structure of compound B?
                        3. What is the intermediate compound formed when compound A reacts with compound B?
                        4. How many molecules of compound A and compound B are needed to form one molecule of intermediate compound C?
                        5. What are the products of the reaction between compound A and compound B?
                        6. Write a balanced chemical equation for the reaction between compound A and compound B.

                        Step 3: Share 

                        To share your work, click on the “Add a new discussion topic” button under this post and paste your work into the “Message” box.

                          1. Given the reaction: A + B <-> C + D, what equations can be written to represent changes in the concentrations and pressures of species A, B, C, and D as the system approaches equilibrium?

                          2. Given a reaction with Kp = 2.3x10^4 atm at 298 K, calculate the reaction quotient, Q, and equilibrium constant, Kc, of the reaction when the reaction mixture has a concentration of [CO2] = 0.0032 M and [CO] = 0.0045 M and a pressure of 1.2 atm.

                          1. Scenario:

                          A chemist is tasked with determining the equilibrium concentrations of a chemical reaction.

                          Using algebra, the chemist sets up an equation to represent the reaction, using the concentration of each species' concentration as variables. The chemist then uses the reaction equation to calculate the equilibrium concentrations of the substances involved in the reaction.

                          Questions:

                          1. What chemical equation is used to represent the reaction?
                          2. How is the equation used to calculate the equilibrium concentrations of the substances involved in the reaction?
                          3. What other factors must be taken into consideration when performing equilibrium calculations?

                          1. Case Scenario:

                          An experiment is conducted to examine the response of a stressed equilibrium when Le Chatelier’s principle is applied. A chemical reaction is used to represent the equilibrium, and the following reaction is written:

                          A + B ⇌ C + D

                          To begin, the reaction is initially set up in its equilibrium state, with the reactants and products present in their equilibrium concentrations. The system is then subjected to a stress, such as a change in temperature, pressure, or concentration of one of the reactants or products. The response of the system can then be observed to determine how the equilibrium has shifted in response to the stress.

                          To determine the response of a stressed equilibrium using Le Chatelier’s principle, it is important to observe the changes that occur in the system. If the stress is an increase in temperature, for instance, the reaction rate will increase, leading to an increase in the concentration of the products. On the other hand, if the stress is a decrease in the concentration of one of the reactants, the reaction rate will decrease, leading to a decrease in the concentration of the products.

                          Question:

                          1. What will happen to the equilibrium concentrations of the reactants and products if the pressure is increased?

                          Step 3: Share 

                          To share your work, click on the “Add a new discussion topic” button under this post and paste your work into the “Message” box.
