Question

Consider a binary liquid mixture at constant temperature T and pressure P . If the enthalpy change of mixing, âˆ†H = 5x1x2, where x1 and x2 are the mole fraction of species 1 and 2 respectively, and the entropy change of mixing âˆ†S = -R[x1 ln x1 + x2 ln x2] (with R = 8.314 J/mol.K), then the minimum value of the Gibbs free energy change of mixing at 300 K occurs when
