恒温恒容平衡体系中的反应物转化率随浓度变化规律的探讨

Change of Fractional Conversion of Reactant with Concentration in Equilibrium System Under Constant,Temperature and Constant Volume

对恒温恒容条件下的可逆平衡体系在增大反应物浓度(即增大反应物的投料)后自身转化率的变化规律,进行了数学推导,得到了其转化率可能减小、不变或增大的结论.通过实例分析佐证了该结论的正确性,以避免在课堂教学和命题中出现错误.

The mathematical derivation was carried out on the change law of fractional conversion of reactant with concentrations in reversible equilibrium system under constant temperature and constant volume. The conclusion had been obtained that the fractional conversion might be reduced, unchanged or increased. Besides, the correctness of conclusion was proved by actual examples, in order to avoid errors in classroom teaching and examination papers.
