Why do hases always tend to be less soluble in liquids as the temperature is raised ?

Text Solution

Verified by Experts

Solubility of gases in liquids decreases with an increase in temperature. This is because is solution of gases in liquids is an exothermic process.
Gas + Liquid `to` Solution + Heat
Therefore, when the temperature is increased, heat is supplied and the equilibrium shifts backwards (exothermic reactions are favoured at low temp. only according to Le - Chaterlie Principle) thereby decreasing the solubility of gases.
