PROPERTIES OF SOLUTIONS: Ch 6 – Chemical Equilibrium References: - Chemical Principles, Steven S. Zumdahl, Fifth Edition, Houghton Mifflin Custom Publishing, Boston, MA - Professor Paul Mc Cord Notes, CH 302, University of Texas at Austin 1 Reactions proceed until the composition of a reaction mixture is described by an equilibrium constant (corresponding to a minimum free energy) that depends on the reaction and on the temperature REACTIONS AT EQUILIBRIUM

Reversibility of Reactions : Ch Equilibrium is the stage in a chemical reaction when there is no further tendency for the composition of the reaction mixture to change. 1. The forward and reverse reaction are both taking places 2. They are doing so at equal rates (no net change) Ch. reactions reach a state of dynamic equilibrium in which the rates of forward and reverse reactions are equal and there is no net change in composition Law of Mass Action : At equilibrium, the composition can be expressed in terms of an equilibrium constant where,
