Chemical Reaction Equilibria

One immediate consequence of Gibbs free energy being minimized is that we can calculate the equilibrium concentrations in a chemical reaction from the molar change in Gibbs free energy of the reaction. The resulting equation is a fraction containing chemical activities raised to stoichiometric powers is equal to an equilibrium constant that can be calculated from $\Delta \ensuremath{\overline{G^{RX}}}$.

This minimization leads directly to what may be a familiar formula for the equilibrium concentrations in a chemical reaction, i.e.,
