研制了基于LabVIEw 7．0 Express的处理电导法测定二级反应速率常数实验数据程序,对反应物初始浓度相等和不等条件下均可处理,避免了人工处理数据的复杂繁琐过程及人工处理过程中的人为误差,提高了实验结果的准确性和重现性。应用结果表明:该程序界面友好,数据处理可视化性强,数据处理结果与文献值比较,反应速率常数k的相对误≤3％,Ea的相对误差<4．5％,结果令人满意。
Based on LabVIEw 7.0 Express, the experimental data program for the determination of the second-order reaction rate constant by the conductivity method was developed. The initial concentration of the reactants can be processed under the same and unequal conditions, which avoids the complicated and complicated process of manual processing data and the manual process In the human error, improve the accuracy and reproducibility of experimental results. The application results show that the program is friendly and the data processing is highly visualized. The data processing results are compared with the literature values. The relative error of the reaction rate constant k is less than or equal to 3%, and the relative error of Ea is less than 4.5%. The result is satisfactory.
