Summary
It has been shown that joined segments of straight lines are observed upon plotting the logarithm of the rate constant against the reciprocal temperature, exhibiting sharp breaks at so-called ‘critical’ temperatures indicating sudden changes in activation energy [3, 5–8]. If the integration of the differential form of theArrhenius equation from 0 toT K is taken into account, the compensation effect can easily be explained.
Zusammenfassung
Wenn man den Logarithmus der Geschwindigkeitskonstante gegen die reziproke Temperatur aufträgt, erhält man aufeinanderfolgende Teilstücke von Geraden mit scharfen Knicks bei sogenannten kritischen Temperaturen, welche jeweils eine Änderung der Aktivierungsenergie anzeigen [3, 5–8]. Integration derArrhenius-Gleichung zwischen 0 undT K führt zu einer zwanglosen Erklärung des Kompensationseffekts.
