In this experiment, several equilibrium systems will be studied. Catalysts have sneaked onto this page under false pretences, because adding a catalyst makes absolutely no difference to the position of equilibrium, and le chatelier s principle doesnt apply to them. Practice using le chateliers principle to predict what happens to a reaction when a stress is applied. This is because a catalyst speeds up the forward and back reaction to the same extent. Since the time when the principle was initially worded, it is common to say that le chatelier s principle is easier to illustrate than to state 4.
