Two open beakers one containing a solvent and the other containing a mixture of that solvent with a non volatile solute are together sealed in a container. Over time:

Moderate

A

the volume of the solution increases and the volume of the solvent decreases
B

the volume of the solution does not change and the volume of the solvent decreases
C

the volume of the solution and the solvent does not change
D

the volume of the solution decreases and the volume of the solvent increases

Solution

The vapour pressure of beaker (II) is less than that of (I) and hence solvent from (I) will evaporate and condense into (II) to make the vapour pressure of baker (II) increase.
