The Haber Process/ The Contact Process 0.0 / 5 ? ChemistryHaber and industrial processesGCSEAQA Created by: HarryCreated on: 23-04-14 18:50 What is 'the haber process'? A very important way of making ammonia (NH4) on a large scale 1 of 9 What does the haber process involve? Reacting N2 gas with H2 gas in a reversible reaction 2 of 9 What is the equation for the reaction between N2 and H2 gas in the haber process? N2 (g) + 3H2 -(reversible reaction sign)-> 2NH3 (g) (exothermic reaction) 3 of 9 What raw materials are needed for the haber process? Air (supplies Nitrogen), Methane (supplies hydrogen) 4 of 9 What are the conditions needed for the haber process? 450 degrees, 200 atmosphere pressure, Iron catalyst 5 of 9 What happens to the ammonia gas that is formed from the reaction? It is COOLED so that it LIQUIFIES and is tapped off as LIQUID AMMONIA 6 of 9 Give a definition of 'Le Chantelier's Principle'? If a reversible reaction is subjected to change, it moves to cancel out that change 7 of 9 What is the reversible reaction for the contact process? Sulfur dioxide + Oxygen -(reversible reaction sign)-> sulfur trioxide 8 of 9 What are the conditions for the contact process? 450 degrees, 1-2 atmospheres, use of Vandanium oxide (V) catalyst 9 of 9
