摘要
用微热量计对亚甲基蓝与溴酸根在水中的氧化还原反应进行了热动力学研究。根据在微量热计上测得的数据和算得该反应的热力学参数(活化焓、活化熵及活化自由能)、数率常数和动力学参数(活化能、指前因子及反应级数),对此反应的机理也作了探讨。
Thermokinetic characteristics of the redox reaction between methylene blue solution and potassium bromate solution was studied by micro-calorimetry. Based on the data obntained with the micro-calorimeter, 3 thermodynamic parameters (i. e. , the activation entmlpy, the activation entropy and the activation free energy), the reaction-rate constant, and 3 kinetic parameters (i. e. , the activation energy, the pre-exponential factor and the reaction order) of the redox reaction were calculated. A discussion on the reaction mechanism was also given.
