Pratima, K. Mishra, Sorendra Prasad, Prem Nigam] Summary: Reactions between CN− and complexes of MnIII withtrans-1, 2-diaminocyclohexanetetraacetic acid (CyDTA) and hydroxyethylethylenediaminetriacetic acid (HEEDTA) have been studied spectrophotometrically at the λmaxS of their respective hydroxo species under pseudo-first-order conditions. The forward reaction is found to be first-order with respect to both the metal complex and [CN−]. The kinetics of the reverse reaction, i.e. the reaction between [Mn(CN)6]3− and CyDTA4− or HEEDTA3− taken in large excess) have been followed spectrophotometrically. In both systems, the reactions follow first-order kinetics each in [Mn(CN)6]3− and the respective ligand concentration and an inverse first-order dependence in [CN−]. A six step mechanism is proposed for the forward reaction where the fifth step is the rate-determining one. pH, ionic strength and temperature dependences have been studied for both systems.
