Vapour pressure of a solution is different from that of pure solvent
(i) Name the law which helps us to determine partial vapour pressure of a volatile component in solution.
(ii) State the above law.

Identify the law which is stated as: For any solution, the partial vapour pressure of each volatile component in the solution is directly proportional to its mole fraction.

Vapour pressure of a solvent containing nonvolatile solute is:

Vapour pressure of the solution of a non- volatile solute is always __.

Partial pressure of solvent in solution of non-volatile solute is given by equation.

If Raoult's law is obeyed, the vapour pressure of the solvent in a solution is directly proportional to

In the depression of freezing point experimet, it is found that: I. The vapour pressure of the solution is less than that of pure solvent. II. The vapour pressure of the solution is more than that of pure solvent. III. Only solute molecules solidify at the freezing point. IV. Only solvent molecules solidify at the freezing point.

The vapour pressure of a solution (P) and the vapour pressure of the solvent (P^(@)) are related to each others as (x_(1) is the mole fraction of solvent)
