The Haber Process

Cards (10)

What kind of reaction is the Haber process
reversible reaction
Where can nitrogen be extracted from?
air
Where can hydrogen be extracted from?
reacting methane with steam
What catalyst is used in the Haber process?
Iron
Describe the Haber process.
the reactants are passed over an iron catalyst at a temperature of 450C and a pressure of 200 atmospheres
How can you use temperature to increase the yield?
cool the ammonia to turn it inot a liquid which is removed
Why do we compromise the pressure at 200 atmospheres when higher pressure produces a greater yield?
high pressure is expensive and dangerous to work with
Is the Haber Process exothermic or endothermic?
exothermic
What effect will a cool temperature have?
shift equilibrium to the right hand side but slows down the reaction
Why is 450 degrees centigrade a compromise?
has a relatively high yield whilst also having a relatively high rate of reaction
