Chapter 12, Problem 79E

One mechanism for the destruction of ozone in the upper atmosphere is

a. Which species is a catalyst?

b. Which species is an intermediate?

c. E_a for the uncatalyzed reaction

${\text{O}}_3\left(g\right)+\text{O}\left(g\right)\to 2{\text{O}}_2\left(g\right)$

is 14.0 kJ. E_a. for the same reaction when catalyzed is 11.9 kJ. What is the ratio of the rate constant for the catalyzed reaction to that for the uncatalyzed reaction at 25°C? Assume that the frequency factor A is the same for each reaction.
