  The purpose of this work is to analyze the mathematical model governing
motion of $n$-component, heat conducting reactive mixture of compressible
gases. We prove sequential stability of weak variational entropy solutions when
the state equation essentially depends on the species concentration and the
species diffusion fluxes depend on gradients of partial pressures. Of crucial
importance for our analysis is the fact that viscosity coefficients vanish on
vacuum and the source terms enjoy the admissibility condition dictated by the
second law of thermodynamics.
