| Abstract: | The existence of the isokinctic relationship (IKR), also called the ‘compensation effect’, is examined for unimolecular reaction series. A statistical analysis on the bases of a common point of intersection of the Arrhenius plots is given. This method is performed using three experimcntal examples. They exhibit highly precise IKRs, showing that this relationship is not necessarily an artefact based on measurement errors. The isokinetic tempcrature, Tiso, of a reaction series is significantly higher in an excess of a mono- atomic inert gas than in gas phase reactions without the inert gas or for reactions in condensed phase. The isokinetic temperature seems to correspond to energy quanta available in the system which can be found in the vibrational spectra of the system. |
