Question

The type of pollution that gets increased during the day time and in the presence of O₃ is :

(1) Reducing smog 

(2) Oxidising smog 

(3) Global warming 

(4) Acid rain

Answer 1

(2) Oxidising smog

In presence of ozone(O₃), oxidising smog gets increased during the day time because automobiles and factories produce main components of the photo chemical smog (oxidising smog) results from the action of sunlight on unsaturated hydrocarbon and nitrogen oxide. 

Ozone is strong oxidising agent and can react with the unburnt hydrocarbons in the polluted air to produce chemicals.
