Answer» The reaction $N_{2} O_{4} (g) ⇌ 2 N O_{2} (g)$ is carried out at 298 K and 20 bar. Five moles of each of $N_{2} O_{4}$ and $N O_{2}$ , are taken initially. Given: $Δ$ $_{f}$ G $^{\circ}$ $N_{2} O_{4} = 100 k J m o l^{- 1}$ and $Δ$ $_{f}$ G $^{\circ}$ $N O_{2} = 50 k J m o l^{- 1}$ . The reaction proceeds at an initial pressure of 20 bar. Determine the direction in which the reaction proceeds to achieve equilibrium. Also determine the amounts of $N_{2} O_{4}$ and $N O_{2}$ when the reaction attains equilibrium.
