N2 - A generalized kinetic model was proposed to describe the kinetics and the deuterium kinetic isotope effect of the epoxidation of ethylene on silver catalysts. The model assumed that ethylene and oxygen adsorbed on different sites, and took into account the overall stoichiometry of the reaction. From the model, it was concluded that the rate of reaction was not limited by the rate of adsorption of oxygen, in spite of the low sticking coefficient of oxygen, and that deuterium labelling of ethylene could result in changes in the surface concentrations of intermediates. This latter point needs to be considered in interpreting kinetic isotope effects in the formation of each of the products.
