  • Chemistry
DEF

A situation in which the freedom of molecules of adsorbate to move about the surface is limited. Adsorption is immobile when kT is small compared to [delta capitalized] E, the energy barrier separating adjacent sites. The adsorbate has little chance of migrating to neighbouring sites and such adsorption is necessarily localized.
