Question

A cylinder filled with a movable piston contains liquid water in equilibrium with water vapour at 25°c . Which one of the following operations results in a decrease in equilibrium vapour pressure?
1. Moving piston downward a short distance
2. Removing a small amount of vapour
3. Removing a small amount of the liquid water
4. Dissolving salt in the water

Open in App

Solution

On dissolving salt in the water becoz on increasing the concentration, forward reaction decreases and hence results in decrease in the equilibrium vapour pressure.

Q. Statement - I
A cylinder fitted with a movable piston contains a certain amount of liquid in equilibrium with its vapor. The temperature of the system is kept constant. If the volume of the vapor is decreased by moving the piston inwards, the vapor pressure will remain unchanged.
Statement - II
Vapor, in equilibrium with its liquid, at constant temperature does not obey Boyle's law.
