In order to decouple the deviations that come from the numerical uncertainties in GCMC enthalpies of adsorption and the deviations coming from the differences between cDFT and GCMC, we also show the comparison of the zero-loading enthalpies of adsorption. These values can be precisely computed with GCMC and are important as they give the temperature dependence of the Henry coefficient. A comparison of the zero-loading enthalpies of adsorption is shown in Fig. .
