Question 2: Given experimental data of equilibrium total pressure at 60C for the vapour-liquid equilibria in methyl-ester and benzene mixture, please (a) plot the ys is xz and (b) Ga is h and compute Ga (partial excess Gibbs energy) at each Xn. (c) Please plot GmiswXB and GmisH$XB i(d) If an azeotrope was formed at Xex0.48 mole at a temperature of 70C and a total pressure of 0.85 har, please conduct van laar model to plot G9 is xa; (e) from (d), please validate the van laar model to this mixture.
