Monitoring and Management >
Chemical processes in industry require monitoring and management to maximise production
Students learn to:
- identify and describe the industrial uses of ammonia
- identify that ammonia can be synthesised from its component gases, nitrogen and hydrogen
- describe that synthesis of ammonia occurs as a reversible reaction that will reach equilibrium
- identify the reaction of hydrogen with nitrogen as exothermic
- explain why the rate of reaction is increased by higher temperatures
- explain why the yield of product in the Haber process is reduced at higher temperatures using Le Chatelier’s principle
- explain why the Haber process is based on a delicate balancing act involving reaction energy, reaction rate and equilibrium
- explain that the use of a catalyst will lower the reaction temperature required and identify the catalyst(s) used in the Haber process
- analyse the impact of increased pressure on the system involved in the Haber process
- explain why monitoring of the reaction vessel used in the Haber process is crucial and discuss the monitoring required
