Some catalytic reactions of cyclo pentanone vapour with hydrogen and with deuterium on evaporated metal films in a static system have been followed by means of a mass spectrometer. Hydrogenation to cyclo pentanol and hydrogenolysis with formation of cyclo pentane and cyclo pentene have been observed to different extents on films of rhodium, palladium, platinum, tungsten and nickel. Kinetic data, activation energies and frequency factors have been obtained for these reduction processes and possible mechanisms are discussed. Similar information has been obtained for the exchange reactions. An order of activity of the metals for inducing fission of the C—O bond is given. Preliminary experiments with cyclo hexanone have indicated an analogous behaviour to that found for cyclo pentanone. A comparison is drawn between the reactions of the cyclic ketones and those found for acetone (Stoddart & Kemball 1956; Kemball & Stoddart 1957).

Kinetics Of Catalytic Reactions

Abstract Resistivity measurements on thin films are very suitable for the study of the kinetics of reactions on metallic surfaces. The oxidation of carbon monoxide on palladium is investigated as an example of great technical relevance, where details of the reaction mechanism and the film structure are well-known from literature. The time dependence of the change in resistivity is quantitatively interpreted with the help of a diffusion model based on a Monte-Carlo simulation of the gas coverage of the surface.
