Haber Process
1 Ammonia made of Hydrogen and Nitrogen
1.1 After gases obtained, they are pumped into a compressor tank
1.1.1 Pressured to 200 atmospheres
1.1.1.1 Heated to 450 degrees in a room with beds on iron catalyst
1.1.1.1.1 Un-reacted products and ammonia go into cooling tank
1.1.1.1.1.1 Ammonia seperated and non-reactants are passed through catalyst again
1.1.1.1.1.1.1 When pressure is increased, gas with least no. of molecules is favoured
1.1.1.1.1.1.1.1 Equilibrium yield of ammonia is increased with pressure
1.1.1.1.1.1.1.1.1 Strong pipes and a lot of energy needed
2 Forward reaction is endothermic; backwards is exothermic
2.1 Exothermic yield decreased with temperature
2.1.1 This causes slower reaction rate
3 Longer the process, the more expensive it is
