A liquid is in equilibrium with its vapour in a sealed container at a fixed temperature. The volume of the container is suddenly increased.
What happens when equilibrium is restored finally and what will be the final vapour pressure?

Solution

At equilibrium, the rate of evaporation is equal to the rate of condensation. The final vapour pressure is equal to the original value.
