Question
Why do gases nearly always tend to be less soluble in liquids as the temperature is raised?
Solution
Answer:
Gas 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 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.
