The excess Gibbs energy of u binary liquid mixture at T and P is given by:
GR/RT = (- 2.6x1 - l.8x2)x1x2
Find expressions for In y1 and In y2 at T and P.
(a) Show that when these expressions are combined in accord with Eq. (11.99) the given equation for GR/RT is recovered.
(b) Show that these expressions satisfy Eq. (11.100), the Gibbs(l)Duhem equation,
(c) Show that (t/ln y1 / dx1) x1 = (d In y y2/dx1)x1=0 = 0.
(d) Plot GE/RT, In y1, and In y2 as calculated by the given equal ion for GE/RT and by the equations developed in (a) vx. X1. Label points In y1∞ and In y2∞ and show their values.
