A mixture of two immiscible liquids `A` and `B`, having vapour pressure in pure state obeys the following relationship if `chi_(A)` and `chi_(B)` are mole fractions of `A` and `B` in vapour phase over the solution

A

If `P'_(A) gt P'_(B)` then `X'_(A) lt X'_(B)`

B

If `P'_(A) gt P'_(B)` then `n_(A) gt n_(B)`

C

`(P'_(A))/(P'_(B)) = (w_(A) xx m_(B))/(m_(A) xx w_(B))`

D

`P'_(A) = P_(M) . X'_(A)`

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
For immiscible liquids
`P'_(A) = P_(M).X'_(A), P'_(B) = P_(M).X'_(B)`
`:. (P'_(A))/(P'_(B)) = (X'_(A))/(X'_(B)) = (n_(A))/(n_(B)) = (w_(A) xx m_(B))/(m_(A) xx w_(B))`
If `P'_(A) gt P'_(B)` then `n_(A) gt n_(B)`
