原理:如果改变影响化学平衡的一个条件,平衡就向能够减弱这种改变的方向移动.适用条件:勒夏特列原理又叫平衡移动原理,只能适用于已达平衡的体系,对未达平衡的体系不能使用.
Principle: If one of the conditions affecting the chemical equilibrium is changed, the equilibrium moves toward the point where the change can be weakened. Applicable conditions: Le Chatelier’s principle is also called the principle of equilibrium movement and can only be applied to a system that has reached equilibrium. Balanced system can not be used.
