Abstract
Adsorption assisted desorption is an important phenomenon in catalytic cycl es. It takes place when a desorption step is not equilibrated. The surface concentration or fugacity of the desorbing species can be higher than its e quilibrium value because of a preceding adsorption step in the catalytic cy cle. This results in an increased rate of desorption. Qualitative and quant itative examples of this effect are discussed. (C) 1999 Elsevier Science B. V. All rights reserved.
