恒温恒压下反应物转化率的讨论

Discussions on conversion ratio of reactants at constant temperature and constant pressure

依据化学平衡原理,在恒温恒压且始态只有反应物而无产物的反应条件下,分析理想气体反应物初始物质的量变化对转化率的影响。结果表明,各反应物初始物质的量维持系数比同时变化时,转化率不变;其余反应物的初始物质的量恒定,某种反应物的初始物质的量变化时,其转化率并不总是其初始物质的量的减函数。

In this paper, according to chemical equilibrium principle, influence of change of initial matter quantity of a reactant on its conversion ratio in the process of ideal gas reaction was discussed at constant temperature, constant pressure and under the condition of having only reactants but not products in initial state. The results indicated when initial matter quantities of various reactants vary simultaneously according to their coefficient ratio, their conversion ratio is constent; when initial matter quantities of other reactants is constent and initial matter quantity of a certain reactant varies, its conversion ratio is not always decreasing function of its initial matter quantity.
