Abstract: A new method for determination of the reaction rate constant in the reversible pseudo first-order reaction was proposed. By this method, the rate constant of ligand exchange reaction between arsenzao Ⅲ coordinating with rare earth and CyDTA was determined. The principle of selecting kinetic data, which were used to calculate the reaction rate constant, was discussed in detail. The kinetic parameters have been applied to the differential kinetic analysis of binary mixture of rare earth with a satisfactory result.

Key words: Heavy rare earth, Kinetic parameter, Rate constant, Differential kinetic analysis
