When molecules of the reactant hit each other, only a certain percentage of the collisions cause a chemical change.If the molecules are moving too slowly, they will bounce off each other. There will be no reaction.If the molecules are moving rapidly but do not collide with the correct orientation, they will again bounce off each other. There will be no reaction.

Answer:
Le Chatelier's principle is an observation about chemical equilibria of reactions. It states that changes in the temperature, pressure, volume, or concentration of a system will result in predictable and opposing changes in the system in order to achieve a new equilibrium state.
