3 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 Qis p the molar ratio of P and Q in the condensed liquid obtained after nth cycle for finite n 1 is A p m C pn 2mn 2 B pm D p mn
