For a binary ideal liquid solution, the total vapour of the solution is given as:

A

`P_("total") = P_A^@ + (P_A^@ -P_B^@)X_B`

B

`P_("total")=P_B^@ + (P_A^@-P_B^@) X_A`

C

`P_("total")=P_B^@+(P_B^@-P_A^@) X_A`

D

`P_("total")=P_B^@ +(P_B^@ - P_A^@)X_B`

Text Solution

Verified by Experts

The correct Answer is:
B
`P = P_A^@x_A + P_B^@x_B = P_B^@ +x_A (P_A^@ - P_B^@) [ :. x_B = 1 - x_A]`

Two liquids A and B are mixed to form an ideal solution. The totol vapour pressure of the solution is 800 mm Hg. Now the mole fractions of liquid A and B are interchanged and the total vapour pressure becomes 600 mm of Hg. Calculate the vapour pressure of A and B in pure form.
