摘　　要：依据褪色分光光度法对BrO_3^--甲基红-NaCl体系进行了研究,实验表明,在518nm为最大吸收波长下,测定了该反应的动力学参数,确定了反应速率方程式,得知该反应的总反应级数为2.5级,表观活化能为55.82kJ/mol,活化能为66.87kJ/mol,实验还测定了其他离子对该反应的催化作用,达到了预期的结果。The system of BrOW--methyl red-NaCl was inyestigated by fading spectrophotometry, the experiment showed that the maximum absorption lied at 518nm,and dynamics parameter of reaction and the reaction speed equation were determined,overall reaction order was obtained as 2.5, both apparent activation energy and activation energy were 55. 82kJ/mol and 66. 87kJ/mol, respectively. The experiment also determined the reaction of catalytic effect for other ion, having the expected results.
