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. |
