P(A)and P(B) are the vapour pressure of ...

`P_(A)and P_(B)` are the vapour pressure of pure liquid components ,Aand B respectively of an ideal binary solution,If `x_(A)` represents the mole fraction of component A, the total pressure of the solution will be

`P_(A)+X_(A)(P_(B)-P_(A))`

`P_(A)+X_(A)(P_(A)-P_(B))`

`P_(B)+X_(A)(P_(B)-P_(A))`

`P_(B)+X_(A)(P_(A)-P_(B))`

Text Solution

Verified by Experts

The correct Answer is:

`P=P_(A)X_(A)+P_(B)X_(B)`
`=P_(A)X_(A)+P_(B)(1-X_(A))`
`implies P_(A)X_(A)+P_(B)-P_(B)X_(A)`
`impliesP_(B)+X_(A)(P_(A)-P_(B))`.
