The kinetics of ethylene oxidation by air over a supported silver catalyst were investigated in the temperature range 490–620 K. The reaction network was found to be triangular. Under virtually constant oxygen partial pressure (0.2 bar), the following rate relationships, (in mol g −1 s −1 ) were found: (formulae in curved brackets denote partial pressures)whereR is expressed in J · mol −1 · K −1 . The given rate expressions are discussed in the framework of earlier kinetic investigations.
