know that many reactions are readily reversible and that they can reach a state of dynamic equilibrium in which:

i) the rate of the forward reaction is equal to the rate of the backward reaction
ii) the concentrations of reactants and products remain constant

be able to predict and justify the qualitative effect of a change in temperature, concentration or pressure on a homogeneous system in equilibrium

evaluate data to explain the necessity, for many industrial processes, to reach a compromise between the yield and the rate of reaction

be able to deduce an expression for K_c , for homogeneous and heterogeneous systems, in terms of equilibrium concentrations
