Equation of the Haber Process

N2 (g)+ 3H2 (g) —> 2NH3

2
New cards

Catalyst used

Iron Catalyst

3
New cards

Why isn’t a high temperature used?

High temp will make a lower yield, because the reaction is reversible, and high temperature will favour the backwards reaction

4
New cards

Why isn’t a low temperature used?

Lower temperature will make a higher yield, but the reaction will be too slow

5
New cards

What temperature is used?

450 degrees - moderate temperature

6

Pressure used

200 atmospheres

  • balance the equilibrium

  • Ensure the equation goes forwards not backwards

  • Reaction favours the side with the fewest moles, 2:4
