P_1and P_2 are the vapour pressures of pure liquid components ,1 and 2

1.	P_1and P_2 are the vapour pressures of pure liquid components ,1 and 2 respectively of an ideal binary solution ifx_1 represents the mole Traction of component1, and the total pressure of the solutions formed by 1 and 2 will be
Answer» `p _(1) + X _(1) (P_(2) -P_(1))` `P_(2) -x _(1) (P_(2) +P_(1))` `P_(1) -x _(2) (P_(1) -P_(2))` `P _(1) + x_(1) (P_(1) -P_(2))` SOLUTION :`P_("TOTAL") = P_(1) + P_(2)` `=P_(1)x_(1) + P_(2) x_(2)""[because x _(1) +x_(2) =1 x _(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))`
