... step of each oxidation should be similar. If that is the case, one might expect the enthalpy and entropy of activation ∆H ‡ and ∆S ‡ to change in a simple way as the chain length of the substrate is increased. The term isokinetic relationship was first defined as a linear dependence of ∆H ‡ on ∆S ‡ ...
