Why does a catalyst increase the rate of a reaction? What is the difference between a homogeneous and a heterogeneous catalyst? Would a given reaction necessarily have the same rate law for both a catalyzed and an uncatalyzed pathway? Explain.
Answer to relevant QuestionsConsider the following potential energy plots for a chemical reaction when answering the questions below. a. Which plot (red or blue) is the catalyzed pathway? How do you know? b. What does ΔE1 represent? c. What does ΔE2 ...Assuming that the mechanism for the hydrogenation of C2H4 given in Section 15.9 is correct, would you predict that the product of the reaction of C2H4 with D2 would be CH2D–CH2D or CHD2–CH3?
