Figure shows the result from the transient simulations of the TPD profiles. Instead of showing the differences, two different curves were plotted along with the ideal model, with only enthalpic coverage effects and with both effects. The TPD profiles from Pt(111) and Co(0001) demonstrate that the enthalpic coverage effect is substantially more impactful, shown by not only the deviation from the ideal assumption profile but also by its proximity to the profile with both effects. Including a coverage-dependent enthalpy shifts the onset of desorption and the peak to lower temperatures for the Pt(111) facet. While the onset is also shifted to lower temperatures for Co(0001), the maximum desorption rate is observed at higher temperatures compared to the ideal case. This shift to higher temperatures clearly displays the stabilizing interactions of CO on Co(0001) in the form of the ( √ 3 × √ 3)R30 • structure. Additionally, the significance of a coverage-dependent entropy is more pronounced for Co(0001) than for Pt(111).
