At `40^(@)C`, the vapour pressures in torr, of methyl alcohol and ethyl alcohol solutions is represented by the equation. `P = 119X_(A) + 135` where `X_(A)` is mole fraction of methyl alcohol, then the value of `underset(x_(A)rarr1)(lim)(P_(A))/(X_(A))` is

A

254 torr

B

135 torr

C

119 torr

D

140 torr

Text Solution

Verified by Experts

`P=119X_(A)+135,lim_(x_(A)to1)(P_(A))/(X_(A))=119+135=254` torr
