【Abstract】 In this paper,the relaxation time was determined at different temperatures by the concentration jump relaxation method.The expression of l/t was derived from the assumed mechanism of reaction.The apparent rate constant and molecular absorbance index were obtained by the concentration-jump relaxation method.The arrhemus activation energy is 52.82 kJ/mol and the activation enthalpy is 50.43 kJ/mol.The activation entropy is a negative in the range of 278 K~298 K.The stability constant of complex is 13.84.These experimental results are in agreement with those obtained by using other methods.更多还原
