|
Answer» Solution :AEROSOLS such as chlorofluorocarbons (CFC's), i.e., freon `(CCl_(2)F_(2))` depletes the `O_(3)` LAYER by SUPPLYING Cl free radicals which convert `O_(3)` to `O_(2)` as shown below : `{:(Cl_(2)CF_(2)(g) overset(hv)rarr. Cl(g) + ."CCLF"_(2)(g)","Cl(g) + O_(3)(g) rarr ClO. (g)+O_(2)(g)),(""ClO.(g) rarr .Cl(g) + . O(g)","ClO.(g) + .O(g) rarr .Cl(g) + O_(2) (g)):}` |
