Abstract

The kinetics of oxidation of DL-aspartic acid by manganese(iii) was studied spectrophotometrically at 500 nm in sulphuric acid medium at 40 degrees C. The reaction was observed to be fractional order with respect to substrate and first order with respect to oxidant. Further the rate of reaction found to decrease with increase in ionic strength and [H+], while [HSO4-] and [Mn-II] were found to have negligible effect. The energy of activation, E-a and the entropy of activation, Delta S-# computed from thermal studies were found to be 102.23 +/- 11.1 KJ mol(-1) and 18.45 +/- 35.40 JK(-1) mol(-1) respectively.
