    Learning Objectives

    WHAT YOU SHOULD BE ABLE TO DO WHEN YOU HAVE FINISHED THIS TOPIC:

    1. Write the equilibrium constant expression for a chemical reaction in terms of either partial pressures or molarities, and interconvert Kp and K for a gas-phase reaction.
    2. Interpret the magnitude of an equilibrium constant.
    3. Evaluate a reaction quotient, and use it to determine the direction of a reaction.
    4. Calculate a value for the equilibrium constant, given appropriate concentrations or gas pressures, and use this value to determine concentrations/pressures in other equilibrium mixtures.
    5. Calculate final concentrations/pressures of reactants and products, given appropriate information about the initial conditions.
    6. Understand and apply le Châtelier’s Principle.
    7. Use the ion product of water (Kw) to relate the concentrations of H+ and OH in an aqueous solution.
    8. Write the Ka expression for an acid, and interpret the numerical value of Ka.
    9. Calculate the pH of a solution of a strong acid or base, calculate the pH of a solution of a weak acid given its Ka value, and calculate the Ka of a weak acid given the pH of a solution of known molarity.
    10. Identify the conjugate acid or base of a given species, and relate the strength of an acid to that of its conjugate base.
