On the Thermodynamics of Chemically Reacting Fluid Mixtures by Morton E. Gurtin This paper develops a thermodynamical theory of chemically reacting, but inviscid, fluid mixtures. Restrictions placed on the constitutive equations by the second law are found. in particular, it is shown that the stress-diffusion matrix is symmetric.
