Abstract

Quaternary gas mixtures which undergo a binary and reversible chemical reaction of the type A+B⇌C+D are analyzed within the framework of Boltzmann equation in order to investigate the effects caused by the reactions on the transport coefficients. The gas system is considered close to chemical equilibrium, a state in which the affinity has a small value characterizing the final stage of a chemical reaction. This kind of the reaction is also known in the literature as fast processes, i.e., processes whose frequencies of the interactions due to chemical reactions is of the same order of the elastic interactions between the constituents of the system. The theory is applied for two known reactions: H2+Cl⇌HCl+H and H+D2⇌HD+D. The coefficients of reaction rate, shear viscosity, thermal conductivity, diffusion and thermal diffusion ratio are analyzed for both reactions by considering the different parameters which characterize these chemical reactions.
