Q. The equilibrium which remains unaffected by change in pressure of the reactants is
A) $N_{2}(g) + O_{2}(g) \rightleftharpoons 2NO(g)$
B) $2SO_{2}(g) + O_{2}(g) \rightleftharpoons 2{SO}_{3}(g)$
C) $2O_{3}(g) \rightleftharpoons 3O_{2}(g)$
D) $2NO_{2} \rightleftharpoons N_{2}O_{4}(g)$
Explanation
(a)
In the reaction, $N_{2}(g) + O_{2}(g) \rightleftharpoons 2NO(g)$, the number of moles of reactants and products are equal, thus it remain unaffected by change in pressure
