The adsorption of ethylene on silver(I) oxide. I. Rates of adsorption

Abstract

The rates of adsorption of ethylene on silver(I) oxide, Ag₂O, have been measured in the temperature range 273-313°K. The kinetic data are analysed in terms of the generalized Elovich equation by methods developed and described in a previous paper.¹ The activation energy derived from the rates at zero coverage is 15.6 kcal mole^-1. The presence of isothermal anomalies is noted and the extent of each kinetic stage defined. A qualitative explanation of the existence of these stages is suggested.
