As we discussed in concept

Breakdown of ozone -

CFCs in stratosphere absorbs UV radiations and form chlorine free radical, which continuously breakdown the ozone.

- wherein

CF_{2}Cl_{2}(g)\rightarrow Cl^{0}(g)+C^{0}F_{2}Cl(g)

Cl^{0}(g)+O_{3}\left ( g \right )\rightarrow ClO^{0}(g)+O_{2}(g)

ClO^{0}\left ( g \right )+O^{0}\left ( g \right )\rightarrow Cl^{0}\left ( g \right )+O_{2}\left ( g \right )

 

 Stratosphere absorbs UV radiations.
