Question

ozone deplection explain with chemical reaction

Answer 1

Answer:

The term ozone depletion means that the destruction of O3 exceeds the creation of O3. When present together in the stratosphere, chlorine (Cl) and ozone quickly react to produce chlorine oxide. Bromine can also act as a catalyst to destroy stratospheric ozone.

Explanation:

Answer 2

Answer:

UV radiations act on dioxygen to form ozone.

There is dynamic equilibrium between the production and decomposition of ozone. The disturbance of this equilibrium results in ozone depletion.

Chlorofluorocarbons mix with atmospheric gases and reach the stratosphere, where they are decomposed by UV rays to produce chlorine free radicals.

These chlorine free radicals react with ozone to form oxygen and ClO⋅ free radicals which react with atomic O to produce more chlorine free radicals.

This results in continuous breakdown of ozone present in the stratosphere damaging the ozone layer.....

formation of ozone molecules:

O2 + UV => O + O

2 O + O2 => 2 O3

depletion of ozone:

O3 + UV => O + O2

O + O3 => 2 O2
