Document Summary

Chapter 16: chemical equilibrium equilibrium: state where the forward and reverse reactions or processes occur at the same rate. Know that concentrations are not changing at equilibrium, but they need not be equal to one another. Be able to indicate when equilibrium is achieved given concentration vs. time plots. Use the law of mass action to write equilibrium expressions for kc or kp for homogeneous and heterogeneous reactions. Include only gases; omit pure liquids and solids. For general reaction, j a + k b l c + m d. For large values of kc or kp (>103), the reaction essentially goes to completion. The equilibrium mixture consists mostly of products (product favored) For small values of kc or kp (<10-3), the reaction does not occur to any significant degree. The equilibrium mixture consists mostly of reactants (reactant favored) For intermediate values (10-3 the equilibrium mixture contains appreciable amounts of both reactants and products.
