Mixture of volatile components A and B h...

Mixture of volatile components A and B has a total vapour pressure (in torr)p=`254-119 x_(A)`is where`x_(A)`mole fraction of A in mixture .Hence`P_(A)^@`and `P_(B)^@`are(in torr)

A

`254,119`

B

`119,254`

C

`135,254`

D

`154,119`

Text Solution

Verified by Experts

The correct Answer is:
C

`P_("total")=254-119chi_(A)`
For `P_(A)^(@): "put" chi_(A) = 1 rArr P_(A)^(@)=135 mm Hg`
For `P_(B)^(@): "put" chi_(A) = 0 rArr P_(B)^(@)=254 mm Hg`
