Abstract
The kinetics of formation reaction of Cd(I) with meso-tetra-meta-tolue ne-porphyrin [H2T(m-CH3)PP] in acetone has been studied by means of st opped-flow method. The proper reaction mechanism was proposed, The eff ects of temperature on the reaction rate were investigated. It was fou nd that k(obs) was reduced with the increase of the ionic strength, th at is, the negative kinetic salt effect was observed. According to Deb ye-Huckel theory and the experimental results a good linear relationsh ip between rate constant and ionic strength was obtained.
