Document Summary

All reactions will reach a state of equilibrium. Both the products and the reactants are present and their concentration does not seem to be changing: reaction is occurring microscopically only, rate of products formed equals the rate of reactants consumed. [(cid:3002)](cid:3276)[(cid:3003)](cid:3277: k is constant only if temperature is constant, small k yields little product, large k goes to completion, solids and liquids do not appear in the equilibrium expression. If rxn3 = rxn1 + rxn2, then k3 = k1k2. Similar to k but all the concentrations are taken at another point in the reaction. If a change is imposed on a system at equilibrium, the position of the equilibrium will shift in the direction that reduce the change. Changes in concentration: reaction will go in the direction that restores concentration. Adding/removing reactants/products: equilibrium will shift such that the concentration of that component is restored.
