A mixture of volatile component A and B ...

A mixture of volatile component `A` and `B` has total vapour pressure (in torr)
`P=254-119chi_(A)`
where `chi_(A)` is the 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

`P_("Total")=254-119chi_(A)` For `P_(A)^(@),` pur `chi_(A)=1impliesP_(A)^(@)=135 mm Hg`
For `P_(B)^(@)` : put `chi_(A)=0impliesP_(B)^(@)=254` mm Hg
