Too Much gramma

Take for instance an endothermic reaction;an increase in temp leads to the formation of product naturally increasing the equilibrium constant(coz equilibrium constant is directly probs to temp) buttt in an exothermic reaction increase in temp causes dicrease in product formation (which means decrease in equilibrium constant)

For an exothermic reaction, when temperature is increased, more energy is released thereby decreasing the equilibrium constant
