        2.10.1 demonstrate understanding that many chemical reactions are reversible and define the terms dynamic equilibrium, homogeneous and heterogeneous;
        2.10.2 deduce the qualitative effects of changes of temperature, pressure, concentration and catalysts on the position of equilibrium for a closed homogeneous system;
        2.10.5 describe and explain the conditions used in industrial processes, for example the Haber process for the formation of ammonia and the Contact process for sulfuric acid; and

      - 8.1 Chemical Equilibrium
        Depth of treatment
        Reversible reactions - dynamic equilibrium. At equilibrium, the rate of the forward reaction equals the rate of the reverse reaction.
      - 8.2 Le Chatlier's Principle
        Depth of treatment
        Le Chatelier's principle. Effect (if any) on equilibrium position of concentration, pressure, temperature and catalyst.
        Social and Applied Aspects
        Industrial application of Le Chatelier's principle in catalytic oxidation of sulfur dioxide to sulfur trioxide and in the Haber process.

      - (d) Equilibria
        In a closed system, reversible reactions attain a state of dynamic equilibrium when the rates of forward and reverse reactions are equal.
        At equilibrium, the concentrations of reactants and products remain constant, but are rarely equal.
        To maximise profits, chemists employ strategies to move the position of equilibrium in favour of the products.
        For a given reversible reaction, the effect of altering temperature or pressure or of adding/removing reactants/products can be predicted.
        The addition of a catalyst increases the rates of the forward and reverse reactions equally. The catalyst increases the rate at which equilibrium is achieved but does not affect the position of equilibrium.
