Reaction Rates in a Deformable Solid in Terms of the Thermodynamics of Irreversible Processes

Based on the thermodynamics of irreversible processes, the relationship between the reaction rate in a deformable solid and the stresses is demonstrated without introducing any additional hypotheses. Well known procedures of accounting for the dependence of the reaction rate on the structure are described. A possible generalization of the classical models by extending the thermodynamics is presented. An example of a transition from the continuum modeling to a two-level modeling is given, which makes it possible to establish a relationship between the parameters affecting the reaction rate at different scale levels. A similar approach can be applied to any scalar process.
