The Haber Process Flashcards
1
Q
What is needed to make ammonia
A
NITROGEN obtained from the air
hydrogen from natural gas or from cracking hydrocarbons
2
Q
What is the equation for making ammonia
A
N2 + 3H2 <=> 2NH3 + heat
Reversible not all hydrogen and nitrogen converted to ammonia as reaches dynamic equilibrium
3
Q
What are the industrial conditions needed
A
Pressure 200 atmospheres
Temperature 450 degrees celsius
Catalyst iron
4
Q
What is the compromise to be made
A
Higher pressure foward reaction good
Higher temp favours backward reaction bad
Lower temp slower rate of reaction
High temp compromise between max yield and speed of reaction
5
Q
How is the ammonia collected
A
Gas turned to liquid in condenser
6
Q
What is ammonia used to make
A
React ammonia with nitric acid
Nitric acid
Ammonium nitrate fertiliser
