摘　　要：在化学动力学教学和科研中,经常涉及到反应速率常数,且要强调各级速率常数的单位。所以在学习和研究中,速率常数的使用,不是十分方便。而标准平衡常数的定义,克服了经验平衡常数单位难以统一的缺点,简化了化学平衡的相关研究和计算。参照标准平衡常数的表达方式,将各级化学反应速率常数的单位统一于mol·dm-3·min-1。In education and research of chemical kinetics,rate constant was constantly concerned,and the unit for every reaction order was emphasized.During in learning and research,the use of rate constants therefore reflects inconvenience.On the other hand,the definition of standard equilibrium constants completely overcame the disadvantage of the experiential equilibrium constants which having no uniform units,and related research and calculations were simplified in a large scale.According to the expression of standard constants in chemical equilibrium,the units of chemical kinetic constants are uniformed in dimension of mol dm-3 min-1.
