What is the initial effect of change on vapour pressure?
(ii) How do rates of evaporation and condensation change initially?
What happens when quilibrium is restored finally and what will be the final vapour pressure?


#2

Decrease in pressure shift the equilibrium in the direction of high pressure i.e., more vapours are formed hence vapour pressure increases.
(ii) Rate of evaporation increases and rate of condensation decreases.
(iii) When equilibrium is restored finally the rate of evaporation again becomes equal to the rate of condensation and the final vapour pressure becomes equal to the vapour pressure that was before the sudden increase in the volume of the container
