One mechanism for the destruction of ozone in the upper atmosphere is O3 (9) + NO(9) → NO,(g) + O2 (9) Slow NO2 (9) + O(g) → NO(g) + O2(9) Fast Overall reaction O3(9) + O(g) → 202 (g) a. Which species is a catalyst? 02 O NO2 03 O NO b. Which species is an intermediate? O 02 O NO2 03 O NO c. E, for the uncatalyzed reaction O3 (9) + 0(g) → 20,(9) is 14.0 kJ. E, for the same reaction when catalyzed is11.9 kJ. What is the ratio of the rate constant for the catalyzed reaction to that for the uncatalyzed reaction at 21°C? Assume the frequency factor A is the same for each reaction. Ratio =
