弹簧模型在判断平衡移动方向上的应用

Spring Model in the Application of Judging the Direction of Equilibrium Move

化学平衡是在一定条件下的暂时动态平衡,当条件改变时,化学平衡将从一个平衡态转变为另一个平衡态。在解决可逆反应的平衡移动问题时,均涉及勒夏特列原理的运用。本文以生活中常见的弹簧形变这一事例,构建一个简单且便于学生领会的弹簧模型来帮助学生轻松判断平衡的移动方向,并通过恰当的例题说明模型的具体运用,以加强学生对平衡移动的领会。

Chemical equilibrium is temporarily dynamic equilibrium under certain conditions,when conditions change,chemical equilibrium will change from one equilibrium state to another state.To solve problems of equilibrium move of reversible reaction,involving the application of Le Chatelier＇s principle.This article take frequently spring deformations in daily life for instance,building a simple and easy spring model to students to help them easily understand to judge the direction of equilibrium move and through appropriate examples,explain the concrete application of the model to enhance students＇ understanding of equilibrium move.
