| Abstract: | The interaction of I-cysteine with hydroxopentaaquarhodium (lIl) has been studied spectrophotometrically as a function of pH, [entering ligand], [substrate] and temperature following the absorption of I-cysteine substituted product at 352 nm. The reaction rate increases with increase in [ligand] and approaches a limiting rate. The values of ΔH¹ (72.6 ± 0.6 kJ) and ΔS¹ (- 91.0 ± 1.8 JK -1 mol- 1) have been calculated from Eyring plot and compared with aqua exchange and analogous ligand substitution processes. An associative interchange mechanism with the ligand participation in the TS is proposed. |
