Habber process Flashcards
Where do raw materials for Haber process come from?
Nitrogen: Air
hydrogen: natural gas. It can be obtained by reacting methane with steam
How are the N and H unreacted used?
Recycled passed through catalyst and more ammonia produced
Why is ammonia cooled after being produced
To make it liquid and remove it
Le chatellier’s principle
If system id equlibrium and something chances the system readjusts
What reaction is the haber process
Exothermic
Why is 450 a compromise temperature?
Relatively fast rate and relatively high yield
How does pressure affect the equilibrium in haber process.
High pressure more ammonia
From a graph how can you say it is exotherimic eaction.
Hugher yield at low temp
Why do not ise a very high pressure.
Lots of energy and dangerous
Iron catalyst
No effects on equilibrium
