Chapter 12, Problem 12.29P

Problems 12.29 through 12.33 refer to the xy diagram provided in Fig. 12.23. This diagram shows xy curves both for ethanol(1)/ethyl acetate(2) and for chloroform(1)/tetrahydrofuran(2), both at a constant pressure of 1 bar. The curves are intentionally unlabeled. Readers should refer to Figs. 12.19 through 12.22 to deduce which curve is for which pair of substances.

 

12.29. What is the composition of the vapor phase in equilibrium with a liquid-phase

ethanol(1)/ethyl acetate(2) mixture of the following compositions at P = 1 bar?

(a) x₁=0.1 (h) x₁= 0.2

1. x₁= 0.3
2. x₁= 0.45
3. x₁= 0.6 (/)x₁= 0.8 (g) x₁= 0.9
