Abstract

If a chemically reacting mixture is confined between two parallel plates, one hot and the other cold, the temperature and the chemical composition at a point, as well as the over-all heat flux, depend upon the rates of both the homogeneous reactions in the gas phase and the heterogeneous reactions on the surfaces. However, if the reaction rates are fast in either the forward or the reverse direction, the assumption of local chemical equilibrium (which is equivalent to the thermodynamics of irreversible processes) is found to be very good. Under such conditions the heat conductivity behaves as though the reacting gas mixture were a pure substance with an effective coefficient of thermal conductivity. A simple equation is given for this effective coefficient of thermal conductivity. Detailed examples are given for a unimolecular rearrangement A⇄B and for the dissociation of oxygen, 02⇄20. The analysis applies equally well to liquid and to gaseous mixtures.
