Question
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 ⎯⎯⎯⎯⎯⎯⎯→ sunlight O2 + O
O3 + Cl ⟶ O2 + ClO
ClO + O ⟶ Cl + O2
(a) Explain why chlorine atoms are catalysts in the gas-phase transformation: 2O3 ⟶ 3O2
(b) Nitric oxide is also involved in the decomposition of ozone by the mechanism:
O3 ⎯⎯⎯⎯⎯⎯⎯→ sunlight O2 + O
O3 + NO ⟶ NO2 + O2
NO2 + O ⟶ NO + O2
Is NO a catalyst for the decomposition? Explain your answer.
