The method of rational thermodynamics of Truesdell's school (non-linear thermomechanics of continuum) has been applied to mixtures of a solid substance with chemically reacting fluids. The kinematics, balances, and stoichiometry in such mixtures are formulated, and constitutive equations are proposed involving the effects of diffusion, heat conduction, and long-term memory expressed by internal parameters. The final form of the constitutive equations has been obtained by applying the constitutive entropic principle of Coleman and Noll. The equilibrium in the mixture is discussed.
