Dynamics of Chemical Reactions: Open Equilibrium [PDF]

open access: yesarXiv, 2000
Dynamic properties of chemical reactions and appropriate relationships for open chemical equilibrium are discussed in approach of the chemical dynamics. New way to calculate composition of chemical systems in open equilibrium, based on the amended equation for the change of Gibbs' free energy, was exemplified using reactions of cobalt double oxides ...
