Abstract

Chemical reactions in an open system are accompanied by direct and reverse transformations of components. In this case, irreversible processes are characterized by production of entropy of both direct and reverse transformations. Negentropy is production of the entropy of the reverse transformation. According to the second law of thermodynamics, production of entropy is a positive value. The difference between production of entropy of direct and reverse transformations (negentropy) is called the useful production of entropy. Negentropy is a barrier to the growth of the useful production of entropy of the system, which not all reactions can overcome. The relationship between the useful production of entropy and negentropy determines the path of evolution of the system at the bifurcation point. Based on the "The Gibbs function normalized to the total number of electrons" and on the example of triangulation of the CaO-SiO2-H2O system, entropy production, negentropy, entropy flux, total entropy change, affinity, thermodynamic force, transformation temperature, rate constant at the interaction of Ca(OH)2 and Ca3Si2O6(OH)2.2H2O are calculated. In chemical reactions, production of entropy and negentropy exist in parallel.
