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. (40% of marks) c) Explain how we can practically achieve the transit of the solution from A to B to C and from A to B1 to 01. (40% of marks) C1 supersaturated с B B1 Concentration A undersaturated Temperature
