摘要：

The effect of adsorbate-induced surface reconstruction on the apparent preexponential factor and activation energy for desorption is analyzed and discussed. The reconstruction is assumed to be a continuous order-disorder phase transition. The adsorbate-induced changes in the surface are shown to result in a rather strong (of the order of 102) coverage dependence of the preexponential factor for desorption. The direction of the variation is in accordance with the compensation effect (the preexponential factor and the activation energy decrease with increasing coverage). © 1990 American Institute of Physics.
