An ideal solution has two components A and B. If A and B .If A is more volatile than B and also PA° > PT then the correct relation between mole fraction of A in liquid (X) and vapour (Y) phase is: (A) XA=YA (B) XA> YA (C) XA < YA (D) Nothing can be said

PA° XA =PT. YA ∴ (XA/YA)=(PT/PA0) < 1 XA < YA

Q. An ideal solution has two components $A$ and $B$ . If $A$ and $B$ .If $A$ is more volatile than $B$ and also $P_{A}^{\circ} > P_{T}$ then the correct relation between mole fraction of $A$ in liquid (X) and vapour (Y) phase is:

$X_{A} = Y_{A}$

$X_{A} > Y_{A}$

$X_{A} < Y_{A}$

Nothing can be said

$P_{A}^{\circ} X_{A} = P_{T} . Y_{A}$
$∴ \frac{X _{A}}{Y _{A}} = \frac{P _{T}}{P _{A}^{0}} < 1$
$X_{A} < Y_{A}$
