This Gibbs energy loss du to reach chemical process molar flow q:
= kf * xA - kb * xB
where kf is the forwar rate coefficient and kb is backward rate coefficient of chemical process; xA is mole fraction os substrate and xB is mole fraction of product. And K = kf/kb = xB/xA is a dissociation coefficient of the chemical process.
