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.

Key words: le Chatelier principle, Shift in equilibrium
