The equilibrium constant. Kp, for the reaction
N₂O₄(g) ⇄ 2NO₂(g)

is 0.113 at 298 K. which corresponds to a standard tree-energy change to 5.4 kJ/mol. certain experiment, the initial pressures are PNâ‚‚Oâ‚„ = 0.453 atm and P NOâ‚‚= 0122 atm. calculate delta G for the reaction at these pressures, and predict the direction in which the reaction with proceed spontaneously to establish equilibrium.
