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

Multiple Choice Options

  • A N2\mathrm{N}_{2} is unreactive in the condition of atmosphere.
  • B Oxides of nitrogen are unstable.
  • C Reaction between them can occur in the presence of a catalyst.
  • D The reaction is endothermic and require very high temperature.

Step-by-Step Verified Solution

N2\mathrm{N}_{2} is unreactive, its reaction with oxides is endothermic and require very high temperature.

N2+O2⇋(1483−2000 K)2NO\mathrm{N}_2+\mathrm{O}_2 \overset{{(1483-2000 \mathrm{~K})}}\leftrightharpoons 2 \mathrm{NO}

(Endothermic and feasible at high temperature)
