Absolutberechnung heterogener Reaktionsgeschwindigkeiten

Summary Experimental results are reported concerning the decomposition of C₂H₅Cl with some chlorides as catalysts. Activation energies were found between 12 and 42 kcal/M, and an exponential relation between activity and activation energy within 8 powers of ten could be verified. A measurement of the surface conditions by adsorption gives some indications of the number of the centres of minimum and maximum activity. On the assumption of a quantum-mechanical leakage of an electron as the rate-determining step the experiments can be evaluated quantitatively in a satisfactory way.
