PROBLEMS FOR SECTION 11.2 11.2-1 a. Show that if two liquids form a regular solution, the critical temperature for phase separation is (81-82) = - 20112V V2 20,02V V2 RT. = (x1V1 + x2V2)3 (81-82)2 = (XV 1 + x2V2) 101 b. Show that the composition at the upper consolute temperature is 107 - 2 = (V} +V2 - V1V 2)1/2 - V1 x1 = 1 X2= ostat on abova V2 - V1 TOL and develop an expression for the upper conso- lute temperature for the regular solution model.
