Figure 12.23: xy diagram for ethanol(1)/ethyl acetate(2) and for chloroform(1)/tetrahydrofuran(2), both at a constant pressure of 1 bar. Note that the curves are intentionally unlabeled, but they can be identified based on information presented in Figs. 12.19 through 12.22 . 2.31. What is the composition of the vapor phase in equilibrium with a liquid-phase chloroform(1)/tetrahydrofuran(2) mixture of the following compositions at P=1 bar? (a) x1=0.1 (b) x1=0.2 (c) x1=0.3 (d) x1=0.45 (e) x1=0.6 (f) x1=0.8 (g) x1=0.9
