Dynamic Equilibrium: a situation in which two reverse processes are occurring at the same rate so that there is no change in the concentration of the reactants or products.
Equilibrium Constant: The value of the equilibrium constant expression for a given reaction. For a given reaction at a given temperature, there will be only one value for the equilibrium constant, no matter how the equilibrium was achieved.
Le Chatelier’s Principle: A change in any of the factors determining the equilibrium will cause the system to adjust so as to reduce or minimize the effect of the change.
Product-favored: A reaction that at equilibrium has more products than reactants.
Reactant-Favored: A reaction that at equilibrium has more reactants than products.
Reaction Quotient: A mathematical expression that relates the concentrations of reactants and products in a chemical reaction. The concentration of the products appear in the numerator and concentrations of the products appear in the denominator. Each of these concentrations is raised to the power of its stoichiometric coefficient in the balanced chemical equation for the reaction.
