The application of temperature scanning methods of kinetic experimentation is explained, documented, and illustrated with two examples. The experimental procedures involved as well as an outline of the required methods of data handling are presented and the advantages of this technique brought out. There is reason to expect that, even without the fitting of rate expressions, TSR data will make it possible to test catalysts rapidly and over broad ranges of reaction conditions, in hours rather than months. It is also expected that the implementation of TS methods for kinetic data gathering will make it possible for fitted kinetic rate expressions to play an important role in guiding mechanistic studies of chemical reactions.
