$N_2(g) + O_2(g) \rightleftharpoons 2NO(g)$

(C) The effect of pressure on the rate of reaction depends on the change in the number of moles of gaseous products and reactants,denoted by $\Delta n_g$.If $\Delta n_g = 0$,the change in pressure does not affect the equilibrium or the rate of reaction.For the reaction $N_2(g) + O_2(g) \rightleftharpoons 2NO(g)$:$\Delta n_g = (n_{products}) - (n_{reactants}) = 2 - (1 + 1) = 0$.Therefore,the rate of this reaction is independent of pressure changes.
