Abstract

The entropy of the activated complex S, calculated from experimental kinetic data, is approximately constant in the series of oxide catalysts used for oxidation of hydrogen, which shows that these contacts are of the same type. The low S values indicate low mobility in the activated complex. A similar result is obtained for the oxidation of carbon monoxide on the oxides. The high S values observed in the oxidation of hydrogen on platinum and palladium indicate surface mobility of the transitional state and also a difference in the nature of metallic and of oxide catalysts for the oxidation of hydrogen.
