An ideal solution has two components A and B. If A is more volatile than B and also `P_(A)^@ gt P_(T)`, then the correct relation between mole fraction of A in liquid `(X)` and vapour `(Y)` phase is :

A

`X_(A)=Y_(A)`

B

`X_(A) gt Y_(A)`

C

`X_(A) lt Y_(A)`

D

Nothing can be said

Text Solution

Verified by Experts

The correct Answer is:
C
`P_(gamma)^(A)X_(A)=P_(T).Y_(A)`
`:. (X_(A))/(Y_(A))=(P_(T))/(P_(A)^(0)) lt 1`
`X_(A) lt Y_A`
