Temperature coefficient of reaction - ScienceDirect
The false image of a classical activation energy could be avoided by calculating - and referring to - a temperature coefficient of reaction, instead of calling it an activation energy" 22_ This would be more accurate and less misleading than the borrowed term and would allow a two- or three-term expansion when necessary to describe the actual data
