Haber process and contact process Flashcards
1
Q
What is the haber process used to make
A
Uses to make ammonia from nitrogen and hydrogen
2
Q
What are the conditions needed
A
A compromise has to be made since it’s a reversible reaction
200 atm pressure
450 degrees c
The higher temperature increases yield but decreases rate so a compromise temperature is made
3
Q
What is the catalyst used in the haber process?
A
Iron
4
Q
What is the contact process used to make
A
It is used to make sulfuric acid
5
Q
Give the chemical equations of the reactions that happen in the contact process
A
S + o2 —> so2
2so2 + o2 —> 2SO3
So3 + h2so4 —> h2s2o7
H2S2O + H2O —> 2H2So4
6
Q
What conditions are needed in the contact process
A
450 degrees c
2 atm pressure
Vanadium (v) oxide catalyst
