Expert Solution

Step 1: Vapour pressure

The liquid molecules tend to convert into the vapour phase. In a closed container, the pressure of vapour at the liquid surface at equilibrium is known as vapour pressure.

The vapor pressure depends on the following factors:

Intramolecular attraction forces: As the strength of intramolecular attraction forces increases, the vapor pressure decreases.
Temperature: As the temperature increases the kinetic energy of the liquid increases and it increases the vapor pressure of the liquid.
