What is the Haber Process used for?
The manufacture of ammonia
1 of 10
What is the word equation for the manufacture of ammonia?
Nitrogen + Hydrogen = Ammonia
2 of 10
Where do we get the Nitrogen and Hydrogen from?
Nitrogen form the atmosphere (Fractional distillation)and hydrogen is from hydration of methane (or from natural gas)
3 of 10
Why is iron used in the Haber Process?
As a catalyst
4 of 10
What is the temprature and pressure they use in the proccess and why?
450° and 200 atmospheres. As it is too expensive to increase the pressure and decrease the temprature and will take too long if the temprature is too low. (450° is comprimise between rate and yield)
5 of 10
What is the average yield from the reaction?
15%
6 of 10
How do they extract the ammonia?
The cool it so it condenses and can be seperated from the unreacted gases
7 of 10
What happens to the excess gases?
They are recycled and but back into the reaction
8 of 10
This is a reversible reaction so what will happen if the temprature is too high?
The yield of ammonia will decrease as production of ammonia is an exothermic reaction (the reaction wil try to decrease the temprature by doing more exothermic reactions)
9 of 10
What happens to the yield of ammonia as pressure increases?
It increases (as the rection will try to reduce pressure by producing ammonia which has less moles then the reactants)
