Easy MCQ +4 / -1 PYQ · JEE Mains 2022

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

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

Solution

$\mathrm{N}_{2}$ is unreactive, its reaction with oxides is endothermic and require very high temperature.<br/><br/> $$ \mathrm{N}_2+\mathrm{O}_2 \overset{{(1483-2000 \mathrm{~K})}}\leftrightharpoons 2 \mathrm{NO} $$<br/><br/> (Endothermic and feasible at high temperature)
