Hi there!❤
Mixing of gases in liquids is an exothermic process,i.e., energy is released in this process. So, according to Le-Chatelier's principle, dissolution of gases in liquids are preferred in low temperature. When the temp. is increased, the rate of dissolution will decrease and may also proceed in the opposite direction.
