An ideal solution has two components A and B. If A is more volatile than B and `P_(A)^@ gt P_(T)`, then the correct relation between mole fractions of A in liquid phase (X) and in vapour phase (Y) 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_(A)^0 X_(A)=P_(T). Y_(A)`
`X_(A)/Y_(A)=P_(T)/P_(A)^0 lt (therefore P_(T) lt P_(A)^0)`
`X_(A) lt Y_(A)`
