An open beaker of water in equilibrium with water vapour is in a sealed container.

Question:

An open beaker of water in equilibrium with water vapour is in a sealed container. When a few grams of glucose are added to the beaker of water, the rate at which water molecules:

  1. leaves the vapour increases

  2. leaves the solution increases

  3. leaves the solution decreases

  4. leaves the vapour decreases


Correct Option: 1

Solution:

The vapour pressure of solution will be less than the vapour pressure of pure solvent, so some vapour molecules will get condensed to maintain new equilibrium.
