A chemical equilibrium is a chemical reaction that is reacting in both directions (forward and backwards) at the same time, and at the same rate. Nothing appears to change (macroscopically - on the large scale), but both reactions are dynamic microscopically.

  • Equilibrium

    7.1 Le Chatelier's principle allows us to predict the behaviour of an equilibrium.

  • The equilibrium law

    17.1 Equilibrium calculations, like mole calculations, need lots of practice.
