Solution: Consider this scenario and answer the following questions: Chlorine atoms resulting from decomposition of chlorofluoromethanes, such as CCl2F2, catalyze the decomposition of ozone in the atmosphere. O

Problem

Consider this scenario and answer the following questions: Chlorine atoms resulting from decomposition of chlorofluoromethanes, such as CCl2F2, catalyze the decomposition of ozone in the atmosphere. One simplified mechanism for the decomposition is:

O3  O2 + O
O3 + Cl ⟶ O2 + ClO
ClO + O ⟶ Cl + O2

(b) Nitric oxide is also involved in the decomposition of ozone by the mechanism:
O3   O2 + O
O3 + NO ⟶ NO2 + O2
NO2 + O ⟶ NO + O2

Is NO a catalyst for the decomposition? Explain your answer.
