Q2: The excess Gibbs energy of a binary liquid mixture at T and P is given by: RTGE=(2.6x11.8x2)x1x2 (a) Find expressions for ln1 and ln2 at T and P. (b) Show that when these expressions are combined in accord with eqn: RTGE=xilni, the given equation for GE/RT is recovered. (c) Show that these expressions satisfy xidlni=0, the Gibbs Duhem equation. (d) Show that (dln1/dx1)x=1=(dln2/dx2)1=0=0 (e) Plot GE/RT, ln1, and ln1 as calculated by the given equation for GE/RT and by the equations developed in (a) vs. x1. Label points ln1 and ln2 and show their values. Q2: The excess Gibbs energy of a binary liquid mixture at T and P is given by: RTGE=(2.6x11.8x2)x1x2 (a) Find expressions for ln1 and ln2 at T and P.
