In this video, Mr. Krug shows students what happens after a chemical reaction at equilibrium has been disturbed, following a chemical concept called Le Chatelier’s Principle. He goes back to the ‘Dance Floor Problem’ to demonstrate mathematically how the principle works, then applies it to various disturbances that could take place in a chemical reaction.
