电量与反应进度的关系式

A formula on the relationship between the charge and the extent of reaction

将反应进度概念用于电极反应,得出了电量与反应进度的关系式Δq=Δξ.zF。通过比较和应用表明,关系式能够全面、确切地解释法拉第定律。该关系式不仅能用于电极反应,对电解的反应物和产物的数量进行计算,而且还能用于电池反应,对电池过程的热力学函数变化进行辅助计算。

A formula △q=△ε·zF on the charge change with the extent of reaction was derived by using the extent of reaction in the electrode reaction. Comparison and application indicated that Faraday＇s law could be precisely explained by the formula all-sidedly. The formula can be used to calculate not only number of moles of electroactive species in the electrode reaction but also variance of thermodynamics function in a cell reaction.
