Formation of Acid Rain

Q.

Dinitrogen and dioxygen are main constituents of air but these do not react with each other to form oxides of nitrogen because-

1. The reaction is endothermic and requires very high temperature.

2. The reaction can be initiated only in presence of acatalyst.

3. Oxides of nitrogen are unstable.

4. Dinitrogen and dioxygen are reactive.
