Which of the following plots represents an ideal binary mixture?

Options

A. plot of `P_("total") v//s 1//X_(B)` is linear `(X_(B) =` mole fraction of 'B' in liquid phase)
B. plot of `P_("total")v//s Y_(A)` is linear `(Y_(B)=` mole fraction of 'A' in vapour phase)
C. plot of `(1)/(P_("total")) v//s Y_(A)` is linear
D. plot of `(1)/(P_("total"))v//s Y_(B)` is non linear

Answer

C

Explanation

`(1)/(P_("total")) = (Y_(A))/(P_(A)^(@)) +(Y_(B))/(P_(B)^(@))`
`(1)/(P_("total")) = (Y_(A))/(P_(A)^(@)) +(1-Y_(A))/(P_(B)^(@))`
`(1)/(P_("total")) = (Y_(A)(P_(B)^(@)-P_(A)^(@)))/(P_(A)^(@)xxP_(B)^(@)) +(1)/(P_(B)^(@))`
