At `40^(@)C` the vapour pressure of pure liquids, benzene and toluene, are `160 mm Hg` and `60 mm Hg` respectively. At the same temperature, the vapour pressure of an equimolar solution of the liquids, assuming the ideal solution will be:

A

`140 mm Hg`

B

`110 mm Hg`

C

`220 mm Hg`

D

`100 mm Hg`

Text Solution

Verified by Experts

The correct Answer is:
B
`P_(m)=160 xx 1/2 +60 xx 1/2 =100 mm`
