For a mixture of two volatile,completely miscible liquids A and B, with P A = 500 torr and P B = 800 torr , What is the composition of last droplet of liquid remaining in equilibrium with vapour?
Provided the initial ideal solution has a composition of x A =0.6 and x B =0.4

Options:

Answer:
C
Solution:

P A o = 5 0 0 torr ; P B o = 8 0 0 torr


When most of the liquid has vaporizedxA=0.6(given) would beyA=0.6
y A = P A o x A P A o x A + P B o 1 - x A
⇒  0.6 = 5 0 0 . x A 5 0 0 x A + 8 0 0 1 - x A
x A = 0.70 ; x B = 0.30
