学习化学工程中判断达到化学平衡状态的标志是许多同学犯难的问题。大多数教师都是从化学平衡状态的定义入手,得出化学平衡的标志:一是,V正=V逆;二是,各组分的物质的量、质量、含量保持不变。笔者认为不能作为化学平衡状态标志的量中一种是不变量,另一种是不能确定能够变为不
Learning chemical engineering to determine the state of chemical equilibrium to determine the sign is a problem many students make difficult. Most teachers start with the definition of chemical equilibrium and get the sign of chemical equilibrium: one is that V is positive and the other is V inverse; the other is that the amount, quality and content of each component remain the same. The author thinks that one of the variables that can not be used as a mark of chemical equilibrium state is invariant and the other is that it can not be determined that it can not become
