The Haber Process

Question 1

What is the haber process used to make

Answer 1

ammonia NH3

Question 2

What is ammonia used to make

Answer 2

fertilisers
nitric acid
explosives

Question 3

How do we get nitrogen for the haber process

Answer 3

N2 from air which is cooled to liquid then fractional distillation to get pure nitrogen

Question 4

what is the formula equation for haber process

Answer 4

N2 + 3H2 —->2NH3
<—-

Question 5

what reaction is exothermic

Answer 5

forward to produce ammonia

Question 6

how do we get hydrogen for haber process

Answer 6

electrolysis of water
or
natural gas
CH4 + 2H2O —> CO2 + 4H2

Question 7

what is the pressure for the haber process and WHY

Answer 7

200 atmospheres because less mols of gas on right so equilibrium favours forward reaction more and any higher the cost would outweigh revenue

Question 8

what is the temperature for haber process and WHY

Answer 8

450 degrees despite the colder conditions producing higher proportion of ammonia it would be too slow reaction

Question 9

what are the conditions for the haber process

Answer 9

450 degrees
200 atmospheres
iron catalyst

Question 10

what happens to unreacted nitrogen and hydrogen

Answer 10

recycled back into reaction
