The approaches presented above are convenient for converting energies into various frameworks such as ab initio thermodynamics and assist in comparing different energy sets while ensuring that all relative quantities for any reaction are conserved. Thus, using these approaches, all microkinetic models will be identical regardless of the choice of anchor species. However, the resulting reaction enthalpies may not be consistent with accurately known enthalpies of the overall gas-phase reaction from global thermochemical networks, such as the ATcT. For example, a reaction enthalpy of 191.2 kJ mol -1 is calculated for C 2 H 6 dehydrogenation with CO 2 at 0 K using BEEF-vdW. This reaction enthalpy is identical for all previously described approaches. However, this value is in stark disagreement with the known reaction enthalpy of 169.7 kJ mol -1 determined from the accurate ∆ f H of the ATcT database. The difference results in an equilibrium constant K for the ODH reaction that is off by a factor of ∼20 for a typical reaction temperature of 873 K as shown in Fig. . Therefore, the methods for comparison and conversion do not lead to microkinetic models that are thermodynamically consistent with the known ∆ f H of gas-phase species. The methods described above are commonly used techniques for manipulating DFT energies in computational catalysis, and lay the foundation for subsequent approaches that enable datasets that are more consistent with known thermochemical information. from the enthalpies of reaction calculated from the ATcT database, the referencing approach, and the referencing approach with corrections. We assumed the same reaction entropy for all different cases. b) Ratio of the equilibrium constants from the computational chemistry methods compared to the exact equilibrium constant derived from the ATcT. Note that the inverse ratio of the referencing approach is shown.
