Haber Process

Question 1

Describe how the haber process works ?

Answer 1

-First methane and air are put in
-Next the gasses are mixed
-Then subjected to very high pressure at 200 atm
-Next they are subjected to high temperatures of 400*c and an Iron catalyst is used here
- it is then cooled down slightly but hydrogen and and nitrogen are still gassed
- ammonia is condensed at is boiling point and comes out as a liquid
- the nitrogen and hydrogen are recycled

Question 2

What does the haber process make ?

Answer 2

Fertilizer

Question 3

What does the Haber process make ?

Answer 3

Fertilizer

Question 4

What are the conditions for the Haber process ?

Answer 4

200 atm so high pressure
High temperature or 400*c

Question 5

What are the compromises ?

Answer 5

Temperature- lower the temp so the equilibrium shirts to the RHS as the forward reaction is exothermic but not to low as it requires activation energy
Pressure- increase pressure so the equilibrium shifts to the RHS because there are fewer molecule but it cannot be to high

Question 6

What is the risk with the Haber process ?

Answer 6

If the pressure is too high it can cause a massive explosion
