Preferred Label : chemical equilibrium;
IUPAC definition : Reversible processes [processes which may be made to proceed in the forward or reverse
direction by the (infinitesimal) change of one variable], ultimately reach a point
where the rates in both directions are identical, so that the system gives the appearance
of having a static composition at which the Gibbs energy, G, is a minimum. At equilibrium
the sum of the chemical potentials of the reactants equals that of the products, so
that: \[Δ G_{{r}} Δ G_{{r}} {o} R\ T\ \ln K 0\] \[Δ G_{{r}} {\,\unicode{x26ac}}
-R\ T\ \ln K\] The equilibrium constant, K, is given by the mass-law effect.;
