在化学平衡教学中,对由化学平衡移动而引发转化率的变化问题,许多学生分不清。笔者根据多年教学经验,总结出转化率变化的一些规律,以方便学生理解和记忆。这里仅就一个已经使用了多年的“经验规律”进行讨论。教师常说:“在某容积固定的容器中,可逆反应mA(g)+
In chemistry-balanced teaching, many students can not distinguish between changes in conversion rates caused by chemical equilibrium shifts. The author based on years of teaching experience, summed up some changes in the conversion rate of law to facilitate students to understand and memory. This is a discussion of ”rules of thumb“ that has been used for many years. Teachers often say: ”In a fixed volume container, reversible reaction mA (g) +
