The Haber Process Flashcards
What is the haber process used to make
ammonia NH3
What is ammonia used to make
fertilisers
nitric acid
explosives
How do we get nitrogen for the haber process
N2 from air which is cooled to liquid then fractional distillation to get pure nitrogen
what is the formula equation for haber process
N2 + 3H2 —->2NH3
<—-
what reaction is exothermic
forward to produce ammonia
how do we get hydrogen for haber process
electrolysis of water
or
natural gas
CH4 + 2H2O —> CO2 + 4H2
what is the pressure for the haber process and WHY
200 atmospheres because less mols of gas on right so equilibrium favours forward reaction more and any higher the cost would outweigh revenue
what is the temperature for haber process and WHY
450 degrees despite the colder conditions producing higher proportion of ammonia it would be too slow reaction
what are the conditions for the haber process
450 degrees
200 atmospheres
iron catalyst
what happens to unreacted nitrogen and hydrogen
recycled back into reaction
