Given at `350Kp_(A)^@=300 "torr"` and `p_(B)^@=800 "torr"` the composition of the mixture having a normal boiling point of `350K` is

A

`X_(A)=0.08`

B

`X_(A)=0.06`

C

`X_(A)=0.04`

D

`X_(A)=0.02`

Text Solution

Verified by Experts

The correct Answer is:
A
`760=300X_(A)+800(1-X_(A))`
`rArr 760=800-500X_(A)`
`rArr 500X_(A)=40`
`therefore X_(A)=(40)/(500)=0.08`.
