Solution

The correct option is A the reaction is endothermic and requires very high temperature
The main component of air are oxygen and they will only react together at a normal temperature. For the formation of oxides of nitrogen, a very high temperature is required.

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants.

Is it necessary that all oxidation reactions are exothermic? If ues then why the reaction for formation of nitrogen oxide an endothermic reaction?
