How does it manufacture ammonia???
Nitrogen from the air and hydrogen fro refinary gases
it is a reversible reaction
use an iron catalyst, about 200 atm and 450degrees C
the temeperature and the pressure is a compromise
the equalibrium would lie more to the right if it was at a lower temperature but then it would take too long to reach an equalibrium
the equilibrium would lie further to the right if the pressure was higher too. but then it would be dangerous and expensive for the equipment so 200atm is a compromise.
the reactants are put into a reactor and they react. the gases are cooled and the ammona liqufies and s tapped off. Because it is a continuous production, any unused gas is recycled and reacted again.
also the ratio of hydrogen to nitrogen put in is 3:1 as then less gas is wasted
the equation 3H2 (g) + N2(g) reversible sign 2NH3
I swear thats how you spell "haber process" :S
Correct me if I'm wrong
It's the correct spelling.
The Haber process is the industrial process used to convert hydrogen and nitrogen into ammonia.
For Edexcel it's pages 194-195 in the Extension book.
Mail me if you need it photocopied.
the reason you may be having difficulties understanding it is because you dont even know how to spell it. First learn the spelling, then try and understand it.
