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

Answer:

Equality of rates of forward and backward processes restores equilibrium. However, the vapour pressure will stay unchanged because it is temperature dependent and not container volume.
