" ix.Vapour pressure of a solution is "

According to Raoult's law, the relative lowering in vapour pressure of a solution is equal to :

The vapour pressure of a solution is proportional to:

Statement Addition of a non-volatile solute causes a depression in vapour pressure. Explanation vapour pressure of a solution is directly proportional to mole fraction of solvent.

The vapour pressure of a solution having solid as solute and liquid as solvent is:

The vapour pressure of a solution having solid as solute and liquid as solvent is:
