A mixture of two miscible volatile ideal liquids P and Q (obeying Raoult’s law) is kept
in a vessel (molar ratio of P and Q in the mixture is m). At a suitable temperature T,
the vapour above the liquid is condensed in another vessel. The liquid obtained on con-
densation is allowed to evaporate and establish equilibrium with its vapour. The vapour
is then condensed in another vessel. The process of such evaporation and condensation
is repeated for n times. If the ratio of the vapour pressure of pure P to that of pure Q is
p, the molar ratio of P and Q in the condensed liquid obtained after nth cycle (for finite
n > 1) is
