Kinetics Study for Copper(Ⅱ) Catalyzed Reaction of Neutral Red with H2O2 in the Medium of NH3·H2O-NH4Cl
【摘要】 本文采用分光光度方法研究了在氨水-氯化氨介质中铜(Ⅱ)催化过氧化氢还原中性红反应的动力学及机理。实验获得速率方程的通式为:r=k[Cu2+]1.0[NR]0[H2O2]1.0,实验活化能Ea=48.98kJ.mol-1。动力学处理导出的方经验速率方程获得满意的吻合。
【Abstract】 We studied the kinetics behaviors of Copper(Ⅱ) catalyzed reaction between neutral red and H2O2 in the medium NH3·H2O-NH4Cl.The common formula of rate law is r=k1.00[H2O2]1.0.Its activation energy is 48.89kJ.The kinetic mechanism was investigated.The rate equation obtained from either mechanism is in conformity with its rate law.
