The impact of CFCs on the ozone layer is amplified by the fact that
A)CFCs replicate in the stratosphere.
B)CFCs decompose before reaching the stratosphere.
C)CFCs react with oxygen to produce many reactive intermediates.
D)one CFC molecule will lead to the decomposition of many ozone molecules.

Question

Quizplus · Accepted Answer

One CFC molecule can lead to the destruction of many ozone molecules because the CFC molecule can catalyze a chain reaction that breaks down ozone molecules in the stratosphere. This reaction occurs when UV radiation from the sun causes the CFC molecule to release a chlorine atom, which then reacts with ozone to form chlorine monoxide and oxygen. The chlorine monoxide molecule can then react with another ozone molecule, releasing another chlorine atom and two oxygen molecules. This process can repeat itself many times, leading to the depletion of the ozone layer.
