Abstract : The report presents the linear and non-linear (i.e. transonic) small perturbation theory for non-equilibrium plane flows. In particular, three different transonic regimes for a singly reacting mixture are defined and the appropriate forms of the corresponding potential equations are derived, interpreted and discussed, especially in connection with their presumable range of uniform validity in the physical space. Seven new types of potential equations are obtained, two linear and the other non linear and of the mixed type. The formal derivation of these equations is implemented by a derivation based on physical interpretations of the contributions given to the kinetic energy and excess power balance equations by the several phenomena occurring during a dynamical evolution of a gas mixture in the presence of rate processes.
