Question 138

Multiple Choice

The photochemical decomposition of chlorofluorocarbons The photochemical decomposition of chlorofluorocarbons was shown to enhance the decomposition of ozone 2 O<sub>3</sub>(g) 3 O<sub>2</sub>(g) Leading to the formation of an ozone hole over the South Pole. In the following mechanism for the decomposition of ozone, characterize the products (ClO, O<sub>2</sub>, and Cl) in each of the two steps. Step 1: Step 2: A) Cl is a catalyst, ClO is an intermediate, and O<sub>2</sub> is a reaction product. B) Cl is an intermediate, ClO is a catalyst, and O<sub>2</sub> is a reaction product. C) Cl and ClO are both catalysts, and O<sub>2</sub> is a reaction product. D) Cl, ClO, and O<sub>2</sub> are all intermediates. E) Cl is a catalyst, and ClO and O<sub>2</sub> are intermediates.
