Question 2: Given experimental data of equilibrium total pressure at 60S for the vapour-liquid equilibria in methyleester and benzene mixture, please (a) plot the a is p and (b) Ga vs g and compute Ge (partial excess Gibbs energy) at each XE (c) Please plot Gmic if XB and GmH \& XB;(d) If an azeotrope was formed at Xex=0.48 mole at a temperature of 70C and a total pressure of 0.85 bar, please conduct van laar model to plot GE: vs Ze; (c) from (d), please validate the van laar model to this mixture. ( 60 points) The vapour pressure of pure methyl-ester at 60 C. 15 0.200 par The vapour pressure of pure benzene at 60C is 0.435 bar The vapour pressure of pure methyl-ester at 70C is 0.312 bar PMVPP The vapoar pressure of pure benzene at 70C is 0.653 bar PB aP
