In a solution of the miscible volatile liquids A and B, the plots of their partical V.P. V_(s) their mole fractions is given by (Assume, V.P. of pure Agt V.P. of pure B) |

Answer»
Partial V.P.(P) of a component in a solution =V.P. of pure component` (P) xx `its mole fraction(X) in the solution i.e.`P_(S)=P_(O) xx x.` This is an EQUATION of a straight line. Hence if `P_(O)` is plotted against x a straight line passing through the origin and with positive slope is obtained. Hence OPTIONS (c) and (d) are incorrect. Now in option (a) and (B), points O and P represent V.P. of pure A and B respectively, and as V.P. of pure A gt V.P. of pure B. The correct option is (a) . |
