Document Summary
Experiment showed a relationship with pressure of reactants and pressure of products: k, is called the equilibrium constant, kc = measured in concentration units, kp = measured in pressure units. The value of k will increase/decrease according to temperature fluctuations and if the reaction is endothermic vs. exothermic. Homogeneous equilibrium all components are in same phase. Heterogeneous equilibrium not all components are in same phase. Solids are not included in equilibrium constant expressions: only gases and liquids. Generally aa + bb cc + dd k = If no gaseous or aqueous products are included, write in a 1 . When reversing equilibrium reactions, equilibrium constant expression must be inverted: k" = 1/k. When equation in equilibrium is multiplied by two, k expression is squared: k" = k2. When equation in equilibrium is divided by two, k expression is square rooted: k" = k1/2. When combining equilibria, multiply the original k expressions together: k" = k1 x k2.
