摘　　要：The thermokinetics of liquid-liqui d reaction of samarium nitrate /dysp rosium nitrate /erbium nitrate with histidine are studied using a microcalorimeter.On the basis of experime ntal and calculated results,three t hermo-dynamic parameters(the activation enthalpy,the active entropy and the activation free energy),the rate constant,three kinetic parameters(the activation energy,the pre-exponential constant and the reaction order)are obtained.The influence of temperature on the t itled reaction and the synthetic con dition of the complex have been discu ssed.The thermokinetics of liquid-liqui d reaction of samarium nitrate /dysp rosium nitrate /erbium nitrate with histidine are studied using a microcalorimeter.On the basis of experime ntal and calculated results,three t hermo-dynamic parameters(the activation enthalpy,the active entropy and the activation free energy),the rate constant,three kinetic parameters(the activation energy,the pre-exponential constant and the reaction order)are obtained.The influence of temperature on the t itled reaction and the synthetic con dition of the complex have been discu ssed.
