3. The activity coefficients of species 1 and 2 in a binary solution are given by: Iny1 = Ax3 In y2 = Ax? In these equations, A is a function of pressure and is given as A = a – BP. Where a and B depend only on temperature. a) Derive and expression to calculate the change in the volume of mixing as a function of composition. b) What are the volumes of mixing for x, = 0 and x2 = 0? At what molar composition is the volume change maximum?
