Query: Reaction-diffusion systems of Maxwell-Stefan type with reversible
  mass-action kinetics   The mass-based Maxwell-Stefan approach to one-phase multicomponent reactive
mixtures is mathematically analyzed. It is shown that the resulting
quasilinear, strongly coupled reaction-diffusion system is locally well-posed
in an $L_p$-setting and generates a local semiflow on its natural state space.
Solutions regularize instantly and become strictly positive if their initial
components are all nonnegative and nontrivial. For a class of reversible
mass-action kinetics, the positive equilibria are identified: these are
precisely the constant chemical equilibria of the system, which may form a
manifold. Here the total free energy of the system is employed which serves as
a Lyapunov function for the system. By the generalized principle of linearized
stability, positive equilibria are proved to be normally stable.
