b) When a substance is transformed from one phase to another, there is a change in the molar Gibbs free energy (AG): AG = H2 - Mi Hi: Chemical potentials of phase 1 - liquid form in solution Hz: Chemical potential of phase 2 - crystal + liquid form in solution Explain the thermodynamic status of the solution at point A, B and C on the diagram. Using AG explain the thermodynamic possibility of spontaneous nucleation to occur at point A, B and C.
