What are the conditions used for the Haber process?
A compromise to balance yield, cost and rate.
What type of catalyst is used?
Iron catalyst
How high is the temperature?
About 450 degrees
How high is the pressure?
About 200 atm
What’s the forward reaction?
Exothermic
What would lowering the temperature do?
It would increase the yield of ammonia, but would also decrease the rate of reaction.
How many gas molecules are on the product side?
Fewer gas molecules on the product side.
What would increasing the pressure do?
It would increase the yield and the rate of reaction.
What’s the disadvantage of increasing pressure?
It’s very expensive to increase the pressure.
Why is iron used as a catalyst?
It’s an effective catalyst for the Haber process.
What does the iron catalyst do?
It doesn’t increase the yield, but does increase the rate.
