Abstract

The paper analyzes the communication matrix coefficients reagiruemostey simple subsystems and the coefficient matrix formed independent subsystems simple reagents chemically reacting systems with chemical kinetics. He showed that the coefficient matrix and the matrix of coefficients reagiruemostey formed independent reagents simple subsystems have the following Items supplied: symmetry; reagiruemostey coefficient matrix in the second subsystem is the sum of simple and symmetric nonnegative definite matrices, at least one of which is positive definite, due to different mechanisms of chemical reactions. Also property of these matrices simple subsystems as matrices susceptibility is positive definiteness of these matrices. The symmetry of these positive- definite matrices follows from the principle of independence stages kinetic mechanism of chemical transformations. Under such constraints matrix corresponds to the general features of the kinetic mechanism of chemical transformations. The paper shows that when comparing potentially streaming method of modeling chemical reactions in a closed system of chemically reacting with traditional chemical kinetics of these two methods are equivalent. Proposed potentially streaming method is preferred in the absence of the detailed mechanism of complex chemically reacting systems. If the total kinetic information is not available, it is preferable to use the proposed potentially streaming method agreed with the non-equilibrium thermodynamics.
