建立反应速率方程的新方法

A New Method for Establishing the Reaction Rate Equation

对于有一定级数的反应,不论反应级数是几,建立反应速率方程时都可以用非线性拟合法来完成。该方法分为两步。第一步,初次对实验数据进行非线性拟合,从而得到反应级数;第二步,借助已得到的反应级数再次对实验数据进行非线性拟合,从而得到反应速率常数。与传统建立反应速率方程的方法相比较,非线性拟合法不仅简单易操作,而且处理结果准确、图线美观大方。

For all reactions with certain reaction order,no matter how the reaction order is,the nonlinear fitting method is applicable. This method can be divided into two steps. In the first step,the reaction order is obtained by nonlinear fitting of the experimental data; in the second step,by the help of reaction order obtained in the first step,the reaction rate constant can be obtained by once more nonlinear fitting of experimental data. Compared with the traditional method of establishing the reaction rate equation,the nonlinear fitting method is easy to operate,and the processing results are concise and accurate.
