Adsorbate-induced surface stress of chloride monolayer on Au(111) electrode

The statistical thermodynamic theory of the absorbate-induced surface stress of adion monolayer on Au(111) is established by using the lattice gas model. The effective pair interaction energy, surface stress, and its components due to various intermolecule forces, and the area elasticity modulus k(sub 2D)(super -1) in the chloride adlayer at the Au(111) electrode surface, are calculated.
