Question: One pathway for the destruction of ozone in the upper

One pathway for the destruction of ozone in the upper atmosphere is
O3(g) + NO(g) → NO2(g) + O2(g) Slow
NO2(g) + O(g) → NO(g) + O2(g) Fast
Overall reaction: O3(g) + O(g) → 2O2(g)
a. Which species is a catalyst?
b. Which species is an intermediate?
c. Ea for the uncatalyzed reaction O3(g) + O(g) → 2O2(g) is 14.0 kJ.
Ea 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 25oC? Assume the frequency factor A is the same for each reaction.
