Question
At equilibrium, the concentrations of reactants and products can
be predicted using the equilibrium constant, Kc, which is a
mathematical expression based on the chemical equation. For
example, in the reaction
aA+bB cC + dD
where a, b, c, and d are the stoichiometric coefficients, the
equilibrium constant is
Ke
=
[C] [D]d
[A] [B]b
where [A], [B], [C], and [D] are the equilibrium concentrations.
If the reaction is not at equilibrium, the quantity can still be
calculated, but it is called the reaction quotient, Qe, instead of the
equilibrium constant, Ke.
