The Harber process and ammonia 0.0 / 5 ? ChemistryHaber and industrial processesGCSEAQA Created by: EllieCreated on: 19-05-13 14:49 What is the Harber process? The production of ammonia 1 of 13 What are Ammonias uses? to make fertilisers and to make nitric acid 2 of 13 What is the chemical equation for the Harber process? N2 + 3H2 = 2NH3 3 of 13 Where is the nitrogen in the harber process obtained from? the air 4 of 13 Where is the hydrogen in the Harber process obtained from? natural gas 5 of 13 What are the industrial conditions required in the harber process? 450 degrees, 200 atmospheres and an iron catalyst 6 of 13 What do you need for maximum yield? low temperatures and high pressure 7 of 13 Why don't we use the conditions required for maximum yield? they'd be too slow and expensive 8 of 13 How is the ammonia separated from the hydrogen and nitrogen? it cools and liquifies and is removed from the nitrogen and hydrogen. 9 of 13 What type of reaction is the Harber process? reversible 10 of 13 What is equilibrium? When the rate of the forward reaction = the rate of the reverse reaction 11 of 13 If we increase the temperature what happens to a reversible reaction? It becomes more endothermic 12 of 13 If we increase the pressure what happens to the pressure? It makes more gas molecules 13 of 13
