The gas phase reaction $2 {NO}_{2} (g) \to N_{2} O_{4} (g)$ is an exothermic reaction. The decomposition of $N_{2} O_{4}$ , in equilibrium mixture of ${NO}_{2} (g) and N_{2} O_{4} (g)$ can be increased by:

Options:

Answer:

Solution:

$2 {NO}_{2} (g) \to N_{2} O_{4} (g) ∆ H = (-) ve$
By addition of inert gas at constant pressure, volume increases and thus, the pressure decreases. The reaction now moves in backward direction as this would increase pressure and hence, decomposition of $N_{2} O_{4}$ increases.
