The Gibbs free energy change determines whether mixing at constant(absolute) temperature and pressure is a spontaneous process. For an ideal solution, the Gibbs free energy of mixing is always negative, meaning that the mixing of ideal solutions is always spontaneous.

dG = -SdT+VdP.
So at constant temperature and pressure dG is 0.
So at constant temperature and pressure dG is 0.
