Question

Explain the relationship between CFCs and Ozone in the stratosphere.

Solution

CFCs find wide use as refrigerants. CFCs discharged in the lower part of atmosphere move upward and reach stratosphere. In stratosphere, UV rays act on them reacting with the Cl atoms. Cl atoms acts as catalysts and degrades ozone releasing molecular oxygen. Cl atoms are not consumed in the reaction. Hence whatever CFC are added to stratosphere, have permanent and continuing effects on ozone level.
