Preferred Label : mobile adsorption;
IUPAC definition : A situation in which molecules of adsorbate are free to move about the surface. Mobility
of the adsorbate will increase with temperature and mobile adsorption may be either
localized or non-localized. In localized mobile adsorption the adsorbate spends most
of the time on the adsorption sites but can migrate or be desorbed and readsorbed
elsewhere. In non-localized adsorption the mobility is so great that a small fraction
of the adsorbed species is on the desorption sites and a large fraction at other positions
on the surface.;
