For an ideal binary liquid solution with `p_(A)^(@) gt p_(B)^(@)` which of the following relations between `x_(A)` (mole fraction of A in liquid phase) and `y_(A)` (mole fraction of A in vapour phase) is correctly represented?

A

`x_(A)=y_(A)`

B

`x_(A)gty_(A)`

C

`x_(A)` lt `y_(A)`

D

`x_(A)` and `y_(A)` cannot be correlated with each other

Text Solution

Verified by Experts

The correct Answer is:
C
`As P_(A)^(0)gtP_(B)^(0), A `is more volatile and hence `Y_(A) gt X_(A)` or `X_(A) lt Y_(A)`

Consider two cylinder piston assembly as shown in figure (a) and in figure (b) are kept in vacuum. Assume both piston are massless. Let two masses m_(1) and m_(2) are kept on the piston as shown in figure. Values of m_(1) and m_(2) are in the range in which both liquid and vapour phase coexist and are in equilibrium. Solution I contains 10 moles of liquid A and 10 moles of liquid B while solution II contains 8 moles of liquid A and 12 moles of liquid B. Let liquids A and B are completely miscible and form an ideal binary solution. Given : P_(A)^(@) = 100 torr, P_(B)^(@) = 60 torr, Let X_(A) = mole fraction of A in liquid phase in solution I X'_(A) = mole fraction of A in liquid phase in solution II Y_(A) = mole fraction of A in vapour phase in solution I Y'_(A) = mole fraction of A in vapour phase in solution II If m_(1) = m_(2) then :
