Describe the Haber process as a reversible reaction between nitrogen and hydrogen to form ammonia
Describe the Haber process as a reversible reaction between nitrogen and hydrogen to form ammonia
**Predict how the rate of attainment of equilibrium is affected by:
a) changes in temperature b) changes in pressure c) changes in concentration d) use of a catalyst**
**Explain how, in industrial reactions, including the Haber process, conditions used are related to:
a) the availability and cost of raw materials and energy supplies b) the control of temperature, pressure and catalyst used produce an acceptable yield in an acceptable time**
Recall that fertilisers may contain nitrogen, phosphorus and potassium compounds to promote plant growth
Describe how ammonia reacts with nitric acid to produce a salt that is used as a fertiliser
Describe and compare:
a) the laboratory preparation of ammonium sulfate from ammonia solution and dilute sulfuric acid on a small scale b) the industrial production of ammonium sulfate, used as a fertiliser, in which several stages are required to produce ammonia and sulfuric acid from their raw materials and the production is carried out on a much larger scale (details of the industrial production of sulfuric acid are not required)
