Local Equilibrium in the Dissolution Kinetics of Ag on Cu(111) Surface

Abstract

The local equilibrium in the kinetic process of dissolution is addressed. The measured dissolution kinetic data of Ag on Cu(111) surface are well fitted by the modified Darken model. Using the obtained fitting parameters, the discontinuous transition of Ag surface concentration against the bulk concentration of the neighboring layers deduced from the local equilibrium model is quantitatively interpreted.
