Problem

Express ∂(ΔG∘)/∂P\partial(\Delta G^\circ)/\partial P in terms of the volumes of solutions of reactants and products, for a chemical reaction of dilute solutes. Plug in some reasonable numbers, to show that a pressure increase of 1 atm has only a negligible effect on the equilibrium constant.
