Please answer all the sections for the the question ... 10.13.

10.13. The molar volume (cm3.mol-l) of a binary liquid mixture at T and P is given by: V = 120x1 + 70x2 + (15x1 + 8x2)x1x2 ; = (a) Find expressions for the partial molar volumes of species 1 and 2 at T and P. (b) Show that when these expressions are combined in accord with Eq. (10.11) the given equation for V is recovered. (c) Show that these expressions satisfy Eq. (10.14), the Gibbs/Duhem equation. (d) Show that (d /dx ),i=1 = (d2/dx1)x1=0 = 0. , (e) Plot values of V, V1, and 72 calculated by the given equation for V and by the equations developed in (a) vs. X1. Label points V1, V2, 79, and 7 2 and show their values. > 1
