Question
Consider the situation where a binary liquid mixture (assume ideal solution) is slowly cooled at constant pressure until it begins to solidify. At the phase equilibrium between the solution and crystal, the chemical potentials of the solvent in each phase must be equal: u** (T,P)= µ"(T,P)+ k;Tlnx ... Equation (1) X, L denotes the crystal and liquid phase, respectively. Since Au = µ*L **: | Aµ = -kgTlnx ... Equation (2) Can you apply Equation (2) at non-phase change temperatures? Why?
