Chemical Equilibrium

	15.1	Write the equilibrium expression for a balanced chemical equation, whether heterogeneous or homogeneous.
	15.2	Numerically evaluate Kc (or Kp ) from a knowledge of the equilibrium concentrations (or pressures) of reactants and products, or from the initial concentrations and the equilibrium concentrations of at least one substance.
	15.3	Interconvert Kc and Kp.
	15.4	Calculate the reaction quotient, Q, and by comparison with the value of Kc or Kp determine whether a reaction is at equilibrium. If it is not at equilibrium,you should be able to predict in which direction it will shift to reach equilibrium.
	15.5	Use the equilibrium constant to calculate equilibrium concentrations.
	15.6	Explain how the relative equilibrium quantities of reactants and products are shifted by changes in temperature, pressure, or the concentrations of substances in the equilibrium reaction.
	15.7	Explain how the change in equilibrium constant with change in temperature is related to the enthalpy change in the reaction.
	15.8	Describe the effect of a catalyst on a system as it approaches equilibrium.
