When q > k, the amount of the products must decrease and the amount of the reactants must increase until equilibrium is established. The reaction will proceed toward the reactants
Chemical equilibrium, condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs. A reversible chemical reaction is one in which the products, as soon as they are formed, react to produce the original reactants.
At equilibrium, the two opposing reactions go on at equal rates, or velocities, and hence there is no net change in the amounts of substances involved. At this point the reaction may be considered to be completed; i.e., for some specified reaction condition, the maximum conversion of reactants to products has been attained. The conditions that pertain to equilibrium may be given quantitative formulation.
For example, for the reversible reaction A ⇋ B + C, the velocity of the reaction to the right, [tex]r_{1}[/tex], is given by the mathematical expression (based on the law of mass action) [tex]r_{1}[/tex]= [tex]k_{1}[/tex](A), where [tex]k_{1}[/tex] is the reaction-rate constant and the symbol in parentheses represents the concentration of A. The velocity of the reaction to the left, [tex]r_{2}[/tex], is [tex]r_{2}[/tex]= [tex]k_{2}[/tex](B)(C). At equilibrium, [tex]r_{1}[/tex]= [tex]r_{2}[/tex], therefore:
[tex]k_{1}(A)_{e} = k_{2} (B)_{e} (C)_{e}[/tex] or
[tex]k_{1}/k_{2} = (B)_{e} (C)_{e}/(A)_{e}=K[/tex]
