Abstract:Kinetics of oxidation of L-valine (Val) by manganese(III) pyrophosphate has been studied as a function of pH (0.94-1.90) at 313 K. The reaction shows a first-order dependence of rate each on [Mn(III)] and [Val] , a fractional-order on [H + ], and an inverse fractional-order each on [Na 4 P 2 O 7 ] and [Mn(II)]. Effects on the rate of anions, such as [F-], [Cl-] and [ClO 4-], and the dielectric constant of the solvent medium have been studied. Solvent isotope studies have been performed in D 2 O medium.
