LEARNING ACTIVITY 8
1. Consider the energy profile below:
Reaction progess
a. How many elementary reactions are in the reaction mechanism?
b. How many intermediates are formed in the reaction?
c. Which step is rate limiting?
d. For the overall reaction, is AE positive, negative, or zero?
2. Consider the mechanism of the iodide-catalyzed decomposition of hydrogen peroxide
H.O:(aq) + I(aq) → H:O() + 10 (aq)
10(aq) + H2O:(aq) - H:O(1) + Oz(g) + I'(aq)
(slow)
(fast)
a. Write the chemical equation for the overall process.
b. Identify the intermediate, if any, in the mechanism.
c. Predict the rate law for the overall process.
