Effect of Temperature
Solubility of gases in liquids decreases with rise in temperature When
dissolved, the gas molecules are present in liquid phase and the process
of dissolution can be considered similar to condensation and heat
is evolved in this process We have learnt in the last Section that
dissolution process involves dynamic equilibrium and thus must
follow Le Chatelier’s Principle As dissolution is an exothermic
process, the solubility should decrease with increase of
temperature
