le Chatelier原理的历史终结

The End of le Chatelier Principle History

100多年以来,经验性的、定性的le Chatelier原理对平衡移动方向的判据经常出现错误。理论证明,le Chatelier原理有严格的条件限制,不是普遍适用的。现代既然有简便的、定量的平衡移动原理,le Chatelier原理应该退出化学教学了。

le Chatelier principle is empirical and qualitative. In fact, it often comes to incorrect results about the shift direction to restore chemical equilibrium, since introduced in 1884. It is proved theoretically that le Chatelier principle′s application conditions are very strict. The modern chemical equilibrium principle is quantitative and legible, and has been taught widely. We propose that le Chatelier principle should not be used in chemical teaching anymore.
