Based on this figure, answer these questions:

a) Starting from a liquid mixture with a composition x1 = 0.4, at which pressure will appear the first vapour? Which will be its composition?

b) If such a mixture is put under 430 mmHg of pressure, which will be the compositions of both phases in equilibrium? And their nliq/nvap mol relation?

c) Under which pressure will the last drop of liquid disappear? Which will be its composition?


Results:
a)p ≈ 465 mmHg, y1 ≈ 0.61; b) x1 ≈ 0.32; y1 ≈ 0.52; nliq/nvap ≈ 1.5; c) p ≈ 390 mmHg, x1 ≈ 0.23;
