4.10.4 The Haber process and the use of NPK fertilisers

Describe the Haber process, including the reactants and products, recycling of remaining hydrogen and nitrogen and the chemical equation

For the Haber process interpret graphs of reaction conditions versus rate

Apply the principles of dynamic equilibrium to the Haber process and discuss the trade-off between the rate of production and the position of equilibrium

Explain how the commercially used conditions for the Haber process are related to the availability and cost of raw materials and energy supplies

Recall the names of the salts produced when phosphate rock is treated with nitric acid, sulfuric acid and phosphoric acid

Describe NPK fertilisers and the compounds they are composed of and compare the industrial production of fertilisers with the laboratory preparations
