Deprotonation of the carboxy groups of 1,3,5‐benzenetricarboxylic acid adsorbed on the Ag(111) surface occurs in the presence of a dilute 2D Cu adatom gas at the surface, while negligible reaction rates occur under similar conditions with Cu in the form of condensed monolayer islands. These results demonstrate that highly mobile adatoms bestow dynamic heterogeneity on materials.
