The equilibrium constant, kp, for the reaction
N₂O₄(g) <_> 2NO₂(g)
is 0.113 at 298 k, which corresponds to a standard free-energy change of 5.4 kj /mol. in a certain experiment, the initial pressures are Pₙ₂ₒ₄ = 0.453 atm and Pₙₒ₂ = 0.122 atm. calculate ∆g for the reaction at these pressures, and predict the direction in which the reaction will proceed spontaneously to establish equilibrium.
