1.	P_(1) and P_(2) are the vapour pressures of pure liquid components,1 and 2 respectively of an ideal binary solution if x_(1) represents the mole fraction of component 1, the total pressure of the solution formed by 1 and 2 will be…..........
Answer» <P>`P_(1)+x_(1)(P_(2)-P_(1))` `P_(2)-x_(1)(P_(2)+P_(1))` `P_(1)-x_(1)(P_(1)+P_(2))` `P_(1)+x_(2)(P_(1)+P_(2))` Solution :`P_("TOTAL")=P_(1)+P_(2)` =`P_(1)x_(1)+P_(2)x_(2)``[becausex_(1)+x_(2)=1x_(1)=1-x_(2)]` =`P_(1)(1-x_(2))+P_(2)x_(2)` =`P_(1)-P_(1)x_(2)+P_(2)x_(2)=P_(1)-x_(2)(P_(1)-P_(2))`
