If 'Delta H_ sot gt0' for a solid, predict the effect of temperatüre on,its solubility?

Text Solution

Verified by Experts

Solid + solvent .harpoons. solution, .triangle H+ve. (endothermic) According to Lechatelier principle.with increase in temperatuie the rate of forward reaction increases ie, eridothermic reaction is favoured. Thus the solubility increases with increase in temperature.
