Lec-11-Chap14-3-Complete 9/28/2009 Chemical Equilibrium Concentrations at equilibrium. Le Chatelier’s Principle 1 Lec-11: Chemical Equilibrium Chapter 14 1 Chemical Equilibrium So far we have learned: 1. How to determine the equilibrium constant K c from initial and equilibrium concentrations. 2. How to determine, given initial concentrations of the reactants and the products, the direction in which the reaction will proceed. C+ D+ A+ B+ a b c d     D A B C c d a b c K the equilibrium constant expression is For a reaction We now consider how to find the composition of a reaction system at equilibrium, given that K c and the initial concentrations are given. 2
