. In class on Wednesday, we defined the availability as A = U + POV - ToS, where Po is the pressure of the surrounding and To is the temperature of the surroundings, which is in contact with a system. Show that for a system at a constant pressure and temperature, dA = dG ≤ 0, which implies that the Gibbs free energy must be minimized for equilibrium to occur.
