(a) Expand CFC.
(b) How does it reduce ozone to oxygen?


#2

(a) Chlorofluorocarbons.
(b) In stratosphere, UV rays act on CFCs thereby releasing Cl, which degrades ozone, releasing molecular oxygen. Cl atoms act merely as catalyst and are not consumed in the reaction. A single chlorine atom can convert 1 Lakh molecules of ozone into oxygen.
