Q-11 Why do gases always tend to be less soluble in liquids as the temperature is raised?


Q-11 Why do gases always tend to be less soluble in liquids as the temperature is raised?
Answer :-
When gas dissolve in liquid it generate a small quantity of heat so we can say that dissolution of gas in a liquid is a exothermic reaction.
Gas + liquid  < --- >  solution  + heat
 According to Le Chatelier's principle when we increase the temperature in a exothermic reaction , the reaction will move to back ward direction that means solution will dissociate and will give gas .Hence with the rise of temperature gas will less soluble.
