When a chemical reaction is at equilibrium, Q (the reaction quotient) is equal toK (the equilibrium constant). If a stress is applied to the mixture that changesthe value of Q, then the system is no longer at equilibrium. To regain equilibrium,the reaction will either proceed forward or in reverse until Q is equal to Konceagain. Alternatively, equilibrium can be disrupted by a change in temperature,which changes the value of K. The result however is the same, and the reactionwill proceed forward or in reverse until Q is equal to the new K. Le Châtelier'sprinciple summarizes this idea:If a stress is applied to a reaction mixture at equilibrium, a net reaction occurs inthe direction that relieves the stress.
