Document Summary

Ch 1020 chapter 14 key terms & textbook notes. Chemical equilibrium: a dynamic process in which the concentrations of reactants and products remain constant over time and the rate of a reaction in the forward direction matches its rate in the reverse direction. Equilibrium constant (k): the value of the ratio of concentration (or partial pressure) terms in the equilibrium constant expression at a specific temperature. Equilibrium constant expression: the ratio of the equilibrium concentrations or partial pressures of products to reactants, each term raised to a power equal to the coefficient of that substance in the balanced chemical equation for the reaction. Mass action expression: equivalent to the equilibrium constant expression, but applied to reaction mixtures that may or may not be at equilibrium. Reaction quotient (q): the numerical value of the mass action expression for any values of the concentrations (or partial pressures) of reactants and products; at equilibrium,
