摘要
研究了溴酸钾氧化甲基橙体系催化动力学测定抗坏血酸(维生素C)的反应动力学规律,实验表明:反应对甲基橙为一级反应,对维生素C也是一级反应,并求得了相应的表观活化能.
The kinetic law of the reaction system, based on the Vc-catalyzed oxidation of methyl-orange (MO) with KBrO3 in nitric acid medium, was studied. The reaction was found to be first order to methyl-orange and Vc respectively. The activation parameters of the reaction have been calculated.
