โœฆ Synopsis

Ahseact

-Taking into consideration our previous results an attempt is made to describe by a theoretical model the transformation processes in underpotential Pb adsorbate on Ag( 111) at low coverages. The results of the model are in good agreement with the experimental data.

## Abstrad-A theoretical model is proposed for the transformation processes in Pb monolayers of high coverages, underpotentially adsorbed on Ag(ll1). The basic assumption is that these processes are due to one-dimensional diffusion from a thin layer which under the experimental conditions is repre

The temperature dependence of the rate constant and the effective diffusion coefficient of incorporation of lead atoms from an underpotential monolayer adsorbate on Ag(ll1) into the silver crystal lattice at low and high coverages is investigated. The transfer activation energy in both cases and the
