| 摘 要： | 研究了KI和（NH4）2S2O8反庆动力学参数的微型化应用操作实验，用废注射器量取溶液，克服了实验教材中用量筒量取溶液的缺点，减少了实验误差，微型实验测定结果符合范特霍夫（J.H.Van't hoff）经验规律，测得活化能Ea的相对误差为1．3％，符合实验要求。

| Abstract: | Miniature experiment was done to determine reaction dy namic parameter of potassium iodide and ammonium persculfate.Miniature dropper a nd injector were used instead of measuring cylinder given by the textbook to ove rcome its shortcoming and reduce experimental error.Experimental results conform ed to Van't Hoff Empirical Law.The error of Ea (Energy of activation) was 1.3% which tallied with experimental demand. |
