Dinitrogen and dioxygen the main constituents of air do not react with each other in atmosphere to form oxides of nitrogen because

Options

  1. AN2{N}_{2} is unreactive in the condition of atmosphere.
  2. BOxides of nitrogen are unstable.
  3. CReaction between them can occur in the presence of a catalyst.
  4. DThe reaction is endothermic and require very high temperature.

Correct answer

D. The reaction is endothermic and require very high temperature.

Step-by-step solution

Dinitrogen and dioxygen are the major constituents of air. These gases do not react with each other to form oxides of nitrogen because the reaction is endothermic and requires very high temperature. The dissociation energy of N2{N}_{2} is very high due to the presence of triple bond and it is very stable.

N2+O2⇄(1483−2000K)2NO{N}_{2} + {O}_{2}\overset{\left(1483 - 2000K\right)}{⇄}2NO
