对《化学反应速率和活化能的测定》实验的探讨

Probe into an Experiment on Determination of the Rate and Activation Energy of Chemical Reaction

对高职高专《无机化学》教材中利用IO3-与SO32-氧-还反应原理设计的化学反应速率和活化能的测定实验进行了探讨,对在t测定时间段内的真实反应和反应物浓度变化的计算进行了分析。认为以该原理设计的实验方法值得商榷,建议更改。

Determination of the rate and activation energy of chemical reaction designed by the principle of reaction 2IO3^-＋5SO3^2-＋2H^＋=5SO4^2-＋I2＋H2O in the textbook of basic inorganic chemical experiment was discussed. The counting for the real chemical reaction and the concentration change of reagent at different intervals was analysed. We consider that the experimental principle on the rate and activation energy determination of the chemical reaction in basic inorganic chemical experiment for higher specialized professional college is complicated.We advanced an improved opinion about the problem.
