Haber Process Flashcards
1
Q
what does the process produce?
A
ammonia for fertilisers
2
Q
endothermic or exothermic?
A
exothermic
3
Q
is it reversible?
A
yes, due to waste products
4
Q
which direction of reaction is exothermic?
A
right
5
Q
how to manipulate reaction
A
change temperature, pressure, taking out produce, putting in reactants for equilibrium to remain right
6
Q
why is 450 degrees used?
A
compromise between low yield and low rate
7
Q
why is 200atm used?
A
compromise between expense and risk
8
Q
why is an iron catalyst used?
A
decrease expense, increased rate in both directions
