    equilibriumstate of a reversible reaction in which the forward and reverse processes occur at equal rates    
    equilibrium constant (K)value of the reaction quotient for a system at equilibrium; may be expressed using concentrations (Kc) or partial pressures (Kp)    
    heterogeneous equilibriaequilibria in which reactants and products occupy two or more different phases    
    homogeneous equilibriaequilibria in which all reactants and products occupy the same phase    
    law of mass actionwhen a reversible reaction has attained equilibrium at a given temperature, the reaction quotient remains constant    
    Le Chatelier’s principlean equilibrium subjected to stress will shift in a way to counter the stress and re-establish equilibrium    
    reaction quotient (Q)mathematical function describing the relative amounts of reactants and products in a reaction mixture; may be expressed in terms of concentrations (Qc) or pressures (Qp)    
    reversible reactionchemical reaction that can proceed in both the forward and reverse directions under given conditions
