Defining the relationship between the activation energy and the enthalpy of each reaction allowed the model to realistically change the kinetics of the microkinetic model. A complete BPE analysis could in theory include all of the parameters in the model, including the E a and pre-exponential factor for each reaction. However, an analysis of this scale would be both computationally expensive and not useful for the task at hand, namely comparing the associated uncertainty for thermodynamic estimation methods.
