According to the related Eyring equation, we can re-interpret the above in terms of Gibbs free energy of activation, along with its relative entropic and enthalpic contributions. However, applying the Eyring equation to catalytic biofilms is not straightforward because of their dynamic and heterogeneous nature. Particularly for EABs, structural changes are known to occur under different flow rates, nutrient concentrations, pH values, electrode potentials, etc., all of which can result in associated variations in the system entropy, thus complicating the definition of a single, well-defined transition state required for the Eyring analysis. Therefore, we forego the thermodynamic framework offered by Eyring, preferring an Arrhenius equation-based analysis as a more practical and empirically accessible approach for analyzing the temperature and flow dependence of EAB reaction kinetics.
