Abstract
The statistical thermod
ynamic theory of adsorbate induced surface stress of anion adsorption monolayer on Au(111) has
been established by using the lattice gas model and considering various components of the adsorbate adsorbate interaction
energies in the adlayer. The adsorbate induced surface stress and its components due to various intermolecule forces of
iodide adions on the Au(111) electrode surface have been calculated. The calculated surface stress of iodide adions on
Au(111) approximates the experiment results. Among vario us components of the adsorbate adsorbate interaction energies in
the adlayer, the substrate mediated interaction is significant for the adsorbate induced surface stress, which shows that
indirect contribution of the adsorption energy of iodide adions thro ugh the substrate mediated interaction is very important..
