Learning Objectives
WHAT YOU SHOULD BE ABLE TO DO WHEN YOU HAVE FINISHED THIS TOPIC:
- 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.
- Interpret the magnitude of an equilibrium constant.
- Evaluate a reaction quotient, and use it to determine the direction of a reaction.
- 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.
- Calculate final concentrations/pressures of reactants and products, given appropriate information about the initial conditions.
- Understand and apply le Châtelier’s Principle.
- Use the ion product of water (Kw) to relate the concentrations of H+ and OH– in an aqueous solution.
- Write the Ka expression for an acid, and interpret the numerical value of Ka.
- 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.
- Identify the conjugate acid or base of a given species, and relate the strength of an acid to that of its conjugate base.
