APPLICATION OF AN EXPONENTIAL TEMPERING FUNCTION TO DESORPTION AND DIFFUSION PROCESSES

The desorption and diffusion of gases from the surface, when exposed to various tempering functions, is reviewed. It is shown that a tempering function of the form T = Toeat is the appropriate form to use, if one wishes to readily interpret activation energies for desorption and diffusion from experimental studies, since this form leads to a linear relation of the temperature at which maximum desorption or diffusion occurred, which is directly proportional to the energy of activation. © 1968.
