Match List - I with List - II
List - I (Laws/properties)List - II (Statements)
(A) Colligative properties(I) for a solution of volatile liquids, the partial vapour pressure of each component of the solution is directly proportional to its mole fraction present in the solution.
(B) Henry's law(II) the total pressure over the solution phase in the container will be the sum of the partial pressures of all the components of the solution.
(C) Raoult's law(III) depends on the number of solute particles, irrespective of their nature.
(D) Dalton's law of partial pressures(IV) at a constant temperature, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas present above the surface of a liquid or solution.
