This Q>K condition says that the reaction will go in reverse. Temperature can also play a role. If a reaction is exothermic we can think of heat as one of the products. Conversely if a reaction is endothermic we can think of heat as one of the reactants. For an endothermic reaction at equilibrium, increasing the tem- perature will shift the reaction out of equilibrium in the reac- tant direction and the system will proceed towards products For an exothermic reaction at equilibrium, increasing the tem- perature will shift the reaction out of equilibrium in the product direction and the system will proceed towards reactants Here too we can view this property in terms of the reaction

Unformatted text preview: quotient. Now, however, it is the equilibrium constant that changes with temperature. For endothermic reactions K ↑ as T ↑ and for exothermic re-actions K ↓ as T ↑ . So, if the system is at equilibrium at one temperature K = Q. If the temperature changes then K changes while Q stays the same. Consequently, K 6 = Q and the system will adjust accordingly. Group Work 1. Let’s say an important drug was produced in a reaction A + B ­ Drug. but the equilibrium constant was small. The reactants A and B are both very expensive. Suggest a way to use THE REACTION QUOTIENT AND LECHATELIER’S PRINCIPLE 39...
