| Abstract: | This paper shows the occurrence of a linear relationship between the activation energy (EA) and the logarithm of the pre-exponential factor (ln A) in the Arrhenius equation, and between the enthalpy increment ( H ) and the entropy increment (S) in the Eyring equation for the reduction of olefinic double bonds by hydrogen transfer over a Pd/sepiolite catalyst. Such a relationship is known as the  compensation effect or isokinetic relationship.
