Chapter 9 Problems Chemistry 101 Dr. Nielson 1. Name one postulate of molecular collision theory. 2. The rate of a reaction depends on 4 things. List two of them and explain how they relate to the rate of a reaction. 3. For a reaction : A + B C . a. Draw an energy diagram where the x-axis is Energy, and the y-axis is the progression of the reaction. The E a is 15 and the ∆ H is -27 for the forward reaction. b. This is a reversible reaction. What is ∆ H for the reverse reaction, C → B + A ? What is the E a for the reverse reaction? 4. Write the equilibrium constant expression for: a. CO(g) + 3 H 2 (g) CH 4 (g) + H 2 O(g) b. C(s) + ½ O 2 (g) CO(g) c. Cu(OH) 2 (s) Cu 2+ (aq) + 2OH - (aq)
