In chemical reactions, bifurcation points are determined by triangulation of a system. With the components interacting, a bifurcation sequence is formed, and the system evolves following one of the branches with formation of a stable compound. Transformations of the components at the point of bifurcation are determined according to "The Gibbs function normalized to the total number of electrons". All conversions are described by the chemical potential, affinity, thermodynamic force. Production of entropy, the flow of entropy and the reaction rate constant allowing the system to choose a specific path of evolutionary conversions have been calculated. The correlation dependence between the chemical potential, affinity, conversion temperature, production and flow of entropy, reaction rate constant is stated.
