Variation of operating pressure reveals the dependency of reaction rate with total concentration expressed in the power-law in eq. ( ). Because of the elementary step assumption, reaction orders, ν i,j , and stoichiometric coefficients, ν i,j , are directly coupled and thus observing reaction order influence simultaneously enables stoichiometric discovery and thus carries important kinetic information. To demonstrate these effects, numerical experiments at varying pressures are conducted. Once again, fig. shows very distinct regions separated into near ambient (p ≤ 10 bar) and high pressures (p > 10 bar). Since adsorption reaction rates are proportional to component partial pressure the adsorptions of reactants A, B and C dominate the reaction network for high pressures (region II) and can be easily identified. This is discernible from approximately equal losses, , for n = 3 and n = 4 in this range, while the integer loss for n = 3 tends towards lower values. This again supports the idea of the fast reaction being found preferably over the slower ones. Table shows the stoichiometric coefficients for the n = 4 reactions identified by the hCRNN for an exemplary experiment at p = 100 bar. Note the deviation in R3 and R4 influencing integer loss. From that it seems that the adsorption of C (reaction R3) is not identified entirely by the hCRNN on its own. Since product adsorption, although possible, is constructed to be severely hindered even at elevated pressures it gets overshadowed by the much faster adsorptions of A and B. However, stoichiometry is reasonably close to the correct coefficients for R3 and stoichiometrically consistent for R4. To illustrate this further, consider fig. . It is apparent that the logarithmic difference in rates strongly increases with higher pressures, meaning stoichiometric discovery can not be guaranteed. However, note that the adsorption of C still takes place significantly fast, when compared to the surface reaction, yet can not quite compete with reactant adsorption of A and B. Nonetheless, its influence is not entirely negligible resulting in a slight increase in loss, , for n = 2 when compared to n = 3 (compare fig. , region II). This in term results in a partial discovery of the product readsorption process at higher pressures. For lower pressures (region I) adsorption rates decrease with decreasing pressure while desorption and surface reaction rates remain constant (compare fig. ). Thus, for low pressures the sorption equilibrium eventually shifts towards desorbed species with net formation rates dominated by the desorption processes, which are independent of pressure. This leads to the identification of n = 4 reactions even to the lowest pressure sampled. Compare again the low and nearly constant overall and integer loss in fig. for n = 4 for low pressures. The stoichiometric consistency of the described hCRNN allows for the identification of all four steps, since the sign (direction) of the reaction step is irrelevant for its stoichiometric discovery by construction, meaning the forward pathway can be discerned from the observed backward reactions.
