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
When `x_(A) = 0, x_(B) = 1`
`:. P = P_(B)^(@)`
`:. P_(B)^(@) = 254`,
when `x_(A) = 1, x_(B) = 0`
`:. P_(A)^(@) = P = 254 - 199 = 135`

At 40^(@)C , the vapour pressure in torr of methyl and ethyl alcohol solutions is represented by P = 119 X_(A)+135 , where X_(A) is mole fraction of methyl alcohol. The value of (P_(B)^(@))/(X_(B)) at lim X_(A) rarr 0) , and (P_(A)^(@))/(X_(A)) at lim X_(B) rarr 0 are:

An ideal mixture of liquids A and B with 2 moles of A and 2 moles of B has a total vapour pressure of 1 atm at a certain temperature. Another mixture with 1 mole of A and 3 moles of B has a vapour pressure greater than 1 atm. But if 4 moles of C are added to second mixture, the vapour pressure comes down to 1 atm. Vapour pressure of C, P_(C)^(@)=0.8 atm. Calculate the vapour pressure of pure A and B :
