Stability of a binary mixture with chemical surface reactions in the general case

In this article we consider the stability of a chemical equilibrium of a thermally conducting two-component reactive viscous mixture, in a horizontal layer heated from below and experiencing a catalyzed chemical reaction at the bottom plate. After reformulating the perturbation evolution equations in a suitable equivalent form, we study the nonlinear Lyapunov stability and, assuming the validity of the principle of exchange of stabilities, we find a region of the parameter space in which the linear and nonlinear stability bounds coincide.
