For a binary ideal lqiuid solutions,the total pressure of the solution is given as

Options

A. `P_("Total")=P_(A)^(**)+(P_(A)^(**)-P_(B)^(**))X_(A)`
B. `P_("Total")=P_(B)^(**)+(P_(A)^(**)-P_(B)^(**))X_(A)`
C. `P_("Total")=P_(A)^(**)+(P_(B)^(**)-P_(A)^(**))X_(A)`
D. `P_("Total")=P_(B)^(**)+(P_(B)^(**)-P_(A)^(**))X_(A)`

Answer

B

Explanation

Since we know
`PT=P_(A)^(**)X_(A)+P_(B)^(**)X_(B)`
`=P_(A)^(**)X_(A)+P_(B)^(**)(1-X_(A))`
`P_(Total)=P_(B)^(**)+(P_(A)^(**)-P_(B)^(**))X_(A)`
