摘要:

动力学数据处理方法是物理化学动力学部分的重要内容之一,其中涉及的经典动力学数据处理方法在面对能提供大量实验数据的现代测试技术时存在不足之处。近期出现的时间变量归一化分析法可较好的解决这些问题,该方法可以只需少数真实实验条件下的实验并结合电子表格软件,通过目视比较即可简单快捷地求出反应物和催化剂的级数以及反应的速率常数。

关键词: 动力学数据, 反应级数, 积分法, 图形化方法

Abstract:

Kinetic data treatment is one of the paramount contents of the kinetics in physical chemistry. There have been imperfections in the classical kinetic data treatment when faced with modern monitoring techniques which can supply extensive experimental data. Recently, variable time normalization analysis is raised to solve the above problems. With only several experiments under real experimental conditions, the rate constant and reaction order of the reactants and catalyst can be deduced by using visual comparison with the help of spreadsheet.

Key words: Kinetic data, Reaction order, Integration method, Visual method
