Chlorofluorocarbons Difficult Ozone exists in equilibrium with oxygen according

Question

Chlorofluorocarbons Difficult Ozone exists in equilibrium with oxygen according to the following reaction: 203-302 Chlorofluorocarbons (CFCs) found in refrigerants and aerosol sprays produce reactive chlorine atoms when released into the atmosphere. Studies have shown that CFCs are main contributors to the destruction of the ozone layer Analyze the following reaction mechanism (1) Cl + O3 ClO + O2 (2) CIO + 03 Cl + 202 Which of the following is the BEST explanation for why CFCs damage our ozone layer? Elimination Tool The rate that the chlorine catalyst destroys ozone is faster than the reverse of the ozone equilibrium reaction. B Cl and ClO shift the ozone equilibrium to the right, producing more oxygen molecules C ClO is an intermediate to the mechanism, allowing more oxygen than ozone to be made D Chlorine acts as a catalyst, speeding up the forward reaction, changing the ozone equilibrium.

Explanation / Answer

(A) The rate that the chlorine catalyst destroys ozone is faster than the reverse of the ozone equilibrium reaction .
