摘　　要：平行反应也称为竞争反应,是理科化学专业物理化学动力学中教学的重点内容之一,也是物理化学考研中常考内容。平行反应中最简单的一类是具有相同级数的不可逆平行反应。在1-1级平行反应动力学方程推导的基础上,阐述级数相同的平行反应的动力学特点、分析温度对级数相同平行反应的影响以及平行反应表观活化能的计算。最后通过例题解析,让同学们进一步理解和掌握具有相同级数的平行反应,同时为物理化学考研的有效复习提供一定的指向。Parallel reaction,also known as competitive reaction,is one of the key contents in Physical Chemistry teaching for Science Chemistry majors,and it is also a common test content in Physical Chemistry postgraduate entrance examination.The simplest type of parallel reactions is irreversible parallel reactions with the same order.Based on the derivation of 1-1 order parallel reaction kinetic equation,the kinetic characteristics of parallel reaction was expounded with the same order,the influence of temperature on parallel reaction was analyzed with the same order,and the apparent activation energy of parallel reaction was calculated.Finally,the example analysis let the students further understand and master the parallel reaction with the same order.At the same time,a certain direction was provided for the effective review of Physical Chemistry postgraduate entrance examination.
