Expert Solution
Step 1

Vapour pressure is the partial pressure exerted by any vapour or gas on the surface of any liquid or solution which is volatile in nature, at equilibrium condition.

Factors affecting Vapour Pressure:-

  • Temperature:- With the increase in temperature, molecule changes into vapour and vapour pressure increases 
  • Boiling point:- Liquid which have lesser boiling point , have high vapour pressure.
  • Purity of liquid:- Pure liquid has always higher vapour pressure as compare to solution.
  • Nature of Liquid:- Liquid which have weak intermolecular force of attraction, have high vapour pressure.
