化学反应速度及活化能测定实验研究

Study on the Determination of Chemical Reaction Speed and Activation Energy

针对化学反应速度及活化能测定实验中经常遇到的困难 ,分析了实验失败的主要原因 ,是由于固体 (NH4) 2 S2 O8试剂中含有少量水而引起的 ,提出了用Na2 SO3 及以痕量碘加速过量Na2 SO3

The determination of chemical reaction speed and activation energy is difficult.The main reason is that there is a little water in ammonium persulfate.In this paper Na 2SO 3 was oxided quickly by trace iodine to eliminate the influence of a little water.
