摘要
The enthalpy change of reaction of zinc chloride with L-α-histidine in thetemperature range of 25-50 ℃ has been determined by a microcalorimeter. On the basis ofexperimental and calculated results, three thermodynamics parameters (the activation enthalpy, theactivation entropy, the activation free energy), the rate constant and three kinetic parameters (theactivation energy, the pre-exponential constant and the reaction order) of the reaction, and thestandard enthalpy of formation of Zn(His)^(2+) (aq.) are obtained. The results showed that the titlereaction easily took place at the studied temperature.
