A general theory for heterogeneous coupled chemical reaction-thermal diffusion systems
Many transport and rate processes in chemical, physical and biological systems, are controlled by the coupled chemical reaction-thermal diffusion process. Though many literatures, including the literatures of engineering of chemical reactions, discussed this coupled problem, but a unified rigorous theory and a unified method based on the chemical thermodynamics are lacked. In this paper we give a general thermodynamic theory including complete energy conservation equation, entropy equation, evolution equations of the heat conduction and the mass diffusion, especially the complete governing equations of these couple systems. The theory given here revises previous theories, clearly shows which factors should be considered and is valuable for the engineering of chemical reaction and other transport and rate processes.
