Question

Which aerosols deplete ozone?

Answer 1

Freons or chlorofluorocarbons (CFCs) are aerosols that accelerate the depletion of ozone. In the presence of ultraviolet radiations, molecules of CFCs break down to form chlorine-free radicals that combine with ozone to form oxygen.

Answer 2

Aerosols like chlorofluorocarbons (CFC’s), i.e., freon (CCl₂F₂), depletes the ozone layer by supplying Cl* free radicals which convert O₃ to O₂

`.Cl(g) + O_3(g) -> ClO.(g) + O_2(g)`

`ClO.(g)+O(g) ->Cl(g) + O_2(g)`
