Spectrophotometric variable-concentration kinetic experiments applied to inorganic reactions

The dependence of the observed rate constant of inorganic substitution reactions on the concentration of nucleophilic reagents was obtained by single variable-parameter kinetic runs. The experiments were carried out spectrophotometrically, varying the concentration of the nucleophile inside the reaction vessel. Software and apparatus were developed for an easy and rapid performance. The method gives accurate results and a saving in time by a factor of up to 100 compared to conventional methods. © 2003 Wiley Periodicals, Inc. Int J Chem Kinet 35: 497–502, 2003
