Understand the reaction quotient,Q, as a non-equilibrium expression of the ratio of reactants and products. Calculate the reaction quotientQfrom the concentrations of reactants and products at a particular time, and determine the direction in which the reaction will proceed to reach equilibrium.
Understand that as a reaction approaches equilibrium, Gbecomes less negative and finally reaches zero. Perform calculations using the equation G= G+ RT lnQ and its application to a system at equilibrium G= -RTlnK.
Understand how the equilibrium constant and Gibbs energy change G, can both be used to measure the position of an equilibrium reaction. Perform calculations using the equation G= -RTlnK.
Solve problems involving values ofKand initial and equilibrium concentrations of the components of an equilibrium mixture. Understand the approximation that [reactant]initial [reactant]eqmwhenKis very small.
