Photochemical smog consists of excessive amount of X , in addition to aldehydes, ketones, peroxy acetyl nitrile (.PAN.). X is: (A) CH4 (B) CO2 (C) O3 (D) CO

Tardigrade Admin · Accepted Answer

Photochemical smog is formed on the chemical reaction of sunlight, nitrogen oxides and volatile organic compounds in the atmosphere.

(NO)_{2} (g) \to h v NO (g) + O (g)

Oxygen atom (nascent) is very reactive and combines with

O_{2}

in air to produce ozone.

O (g) + O_{2} (g) \to O_{3} (g)
