Describe the Haber process as a reversible reaction between nitrogen and hydrogen to form ammonia
#5.20C
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
#5.21C
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
#5.22C
Recall that fertilisers may contain nitrogen, phosphorus and potassium compounds to promote plant growth
#5.23C
Describe how ammonia reacts with nitric acid to produce a salt that is used as a fertiliser
#5.24C
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)
