The Destruction of the Ozone Layer by Chlorofluorocarbons Can Be

question 49

Short Answer

The destruction of the ozone layer by chlorofluorocarbons can be described by the following reactions, all occurring in the gas phase.
ClO + O₃  Cl + 2O₂
H°_rxn = -29.90 kJ
2O₃  3O₂
H°_rxn =
Cl + O₃  ClO + O₂
H°_rxn = 54.08 kJ
What is H°_rxn for the decomposition of ozone to oxygen?
