Abstract: Thermodynamics of physicochemical processes in a reversibly reacting distributed kinetic system is considered, and nonequilibrium entropy of autowaves of laminar combustion is constructed. A qualitative and numerical analysis of the local and total entropy production in the system is performed. The total entropy production is shown to be a functional on integral curves, possessing extreme properties, whose minimum corresponds to the only physically meaningful solution of the problem. The results of solving problems with kinetic equations that take into account the reversible or irreversible character of the chemical reaction are compared.

Keywords: nonequilibrium thermodynamics, laminar combustion, autowave, entropy production.
