By the end you’ll be able to

recognise and write reversible reactions using the reversible arrow and distinguish reversible from irreversible changes
describe dynamic equilibrium as a closed-system state in which the forward and reverse reactions continue at equal rates so the concentrations of reactants and products remain constant
predict the effect of changing concentration on the position of equilibrium using Le Chatelier’s principle

predict the effect of changing pressure on the position of equilibrium in gaseous systems by considering the side with fewer or more moles of gas

explain and evaluate the conditions used in the Haber process, including temperature, pressure, iron catalyst and continuous removal of ammonia, as a compromise between rate, yield and cost
