The effect of decrease in temperature on given substance and value of equilibrium constant K has to be explained. Concept Introduction: Le Chatelier principle states that, whenever a change in temperature, pressure or volume is experienced by a system at equilibrium, the system will undergo reactions to cancel that effect and reattain equilibrium. The equilibrium constant K will change with change in temperature. For a reaction, if the enthalpy of reaction is negative then that reaction will be exothermic , that is, heat is liberated during the reaction. If enthalpy of reaction is positive then that reaction is endothermic , that is, the heat is absorbed during the reaction. If the forward reaction is exothermic, then, to increases the products, temperature should be lowered. If the product is more, then equilibrium constant (K) will be more. Similarly in the case of endothermic reaction, increase in the temperature causes the increase in the amount of products.
