For an ideal binary liquid solution with P°A > P°B which relation between XA (mole fraction of A in liquid phase) & YA (mole fraction of A in vapour phase) is correct. XB & YB are mole fractions of B in liquid & vapour phase respectively-
XA = YA
XA > YA
XA/XB < YA/YB
XA, YA, XB, YB cannot be correlated
Since P°A > P°B, A is more volatile. Hence vapour phase is richer in A: YA > XA Therefore: YA/YB > XA/XB ⇒ XA/XB < YA/YB
