Question
Which aerosols deplete ozone?
Solution 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.
Solution 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)`
