Many homologous reaction series present linear correlations between the enthalpy ( $$\Delta H_{{ \ne {\text{,i}}}}^{{\text{o}}}$$ ) and entropy ( $$\Delta S_{{ \ne {\text{,i}}}}^{{{\text{ o}}}}$$ ) of activation (kinetic compensation effect), the slo

The oxidation of hexacyanoferrate(ll) ion by a large excess of hydrogen peroxide, in slightly acidic aqueous media containing potassium dihydrogen phosphate (pH 5.10 ± 0.05), was followed by monitoring the increase of absorbance at 420 nm as the col

The redox reaction between hexacyanoferrate(II) ion as the reducing agent and hydrogen peroxide as the oxidizing one, in slightly acid (pH 4.36-6.65) aqueous solutions containing phosphate ions, has been studied by means of an UV-Vis spectrophotomete

Random experimental errors are known to provoke the appearance of false isokinetic enthalpy–entropy relationships under some circumstances. In this contribution, it is shown that the observation of a false error-caused isokinetic plot, with a slope

The kinetics of the reaction of substitution of aqua ligands in Cr(III) complexes by the amino acid l-histidine, in aqueous media and under acidic conditions (pH 3.60–5.79), has been studied with the aid of a spectrophotometric technique (at 530 nm

The ligand sequential replacement on chromium(III)-aqua complexes by L-alanine in slightly acidic aqueous solutions (pH range: 3.55-5.61) has been kinetically followed by means of UV-Vis spectrophotometry. A two rate constant model has been applied t

The elementary reaction sequence A ↔ I → P is the simplest mechanism for which the steady-state and quasi-equilibrium kinetic approximations can be applied. The exact integrated solutions for this chemical system allow inferring the conditions th

Many kinetic studies concerning homologous reaction series report the existence of an activation enthalpy-entropy linear correlation (compensation plot), its slope being the temperature at which all the members of the series have the same rate consta
