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
