CHM 206 Spring 2008Dr. LoganCH 16 Learning Objectives Chapter 16: Principles of Reactivity: Chemical EquilibriaKnow and be able to usethe key equations, found on p. 789, as well as the ones described below.Understand the nature and characteristics of chemical equilibriaa.Chemical reactions are reversible and equilibria are dynamic: a reaction is at equilibrium when the rate of the forward reaction is equal to the rate of the reverse reaction.b.Understand that the magnitude of K and the time required for a reaction to reach equilibrium are notrelated.Understand the significance of the equilibrium constant, K, and the reaction quotient, Q.a.Write the reaction quotient, Q, for a chemical reaction. Know that when the system is at equilibrium, Q = K, the equilibrium constant for the chemical reaction as written, at a given temperature.b.Know that Q and K are dimensionless.c.Recognize that the concentrations of solids, pure liquids, and solvents (e.g., water) that are present are not included in the equilibrium constant expression.
