Consider a binary mixture of volatile liquides. If at `X_(A)=0.4`, the vapour pressure of solution is 580 torr then the mixture could be `(p_A^@=300 "torr" ,P_(B)^@=800 "torr")` :

A

`CHCl_(3)-CH_(3)COCH_(3)`

B

`C_(6)H_(5)Cl-C_(6)H_(5)Br`

C

`C_(6)H_(6)-C_(6)-C_(6)H_(5)CH_(3)`

D

`nC_(6)H_(14)` and `C_(6)H_(5)CH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
It shows negative deviation from Raoult's law
`P_(s)` (actual) `=580` torr
`P_(s)` (Raoult) `=0.4xx300+0.6xx800=600` torr.
