Kinetics and volumes of activation of the reactions of nickel(II) and cobalt(II) ions with some uncharged ligands in water, studied by a laser temperature-jump method at high pressures

Abstract

The volumes of activation ΔV‡ for the reactions of Ni^II and Co^II ions with some uncharged ligands in water were determined from kinetic measurements in a laser temperature-jump apparatus, in which rates could be determined spectrophotometrically at pressures up to several kbar; the values are all ca. 7–9 cm³ mol^–1.
