Abstract

A discussion is presented on the relation between true and apparent activation energies found in heterogeneous catalysis. The possibility of a transient species defining the rate determining step is emphasized. In such a case, the difference between apparent and true activation energies can be quite small. Such a condition is of importance for the understanding of phenomena involving the activation energy, such as the isokinetic effect.
