QUESTION 2.11

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

Open in App

Solution

Gas + Liquid $⇌$ Dissolving gas; $Δ H = - v e$ . Dissolution of gas is an exothermic process. As the temperature is raised, the equilibrium shifts in reverse direction (Le-Chatelier's principle). It results in decrease of solubility of gases in liquid.
