For an ideal binary liquid solution with `P_A^@ gt P_B^@` which relation between `X_A` (mole fraction of A in liquid phase) and Y(mole fraction of A in vapour phase) is correct, `X_B and Y_B` are mole fraction of B in liquid and vapour phase respectively

A

`X_A = Y_A`

B

`X_A gt Y_A`

C

`X_A/X_B lt Y_A/Y_B`

D

`X_A1,Y_A, X_B and Y_B` cannot be correlated

Text Solution

Verified by Experts

The correct Answer is:
C
`P._A = P_A^@ . X_A = P_T.Y_A`
`P._B= P_B^@.X_B = P_T. Y_B`
`:. (P_A^@)/(P_B^@)*(X_A)/(X_B)=(Y_A)/(Y_B) :. (P_A^@)/(P_B^@)*(X_A)/(X_B)lt (Y_A)/(Y_B)`
