Haber Process Flashcards
1
Q
Industrial conditions
A
- Pressure = 200 atmospheres
- Temperature = 450
- Catalyst = iron
2
Q
equation
A
N2 (g) + 3H2 (g) = 2NH3 (g) + (heat)
3
Q
pressure
A
High pressure to favour foward recation as fewer molecules
4
Q
temperature
A
Low temperature better as exothermic but would result in slow rate of reaction so high temperature is used
5
Q
ammonia
A
formed as a gas but cools in the condenser so liquefies
6
Q
hydrogen and nitrogen
A
unused hydrogen and nitrogen are recycled so nothing is wasted
7
Q
catalyst
A
iron catalyst speeds up the rrate of the reaction but doesnt affect the % yield
8
Q
uses of ammonia
A
- used in Ostwald process to make nitic acid
- react with nitric aciod for fertilizers
