Given are the following informations at 298 K.
$\begin{array}{llr} N_{2} O_{4} (g) ⇌ 2 {NO}_{2} (g) \\ Δ_{f} H^{\circ} / kJ {mol}^{- 1} 9.16 33.18 \\ Δ_{f} G^{\circ} / kJ {mol}^{- 1} 97.54 51.31 \end{array}$
The reaction is carried out in a closed vessel starting from $N_{2} O_{4}$
The reaction is started with $N_{2} O_{4}$ (g) along with a suitable catalyst. The degree of dissociation at equilibrium.
