The kinetics of substitution of aquo ligands from hydroxopentaaquo chromium (III) ion by L-histidine in water ethanol medium has been studied spectrophotometrically. The rate law involving the ion pair formation has been established. The activation parameters have been calculated and compared with other substitution reactions. Variation of dielectric constant of the medium was used as a tool for the mechanistic conclusion. Considering all the results, a mechanism involving the prior formation of ion pair followed by associative interchange (Ia) has been suggested. |
