Changing conditions for the Haber process

N₂ + 3H₂ ⇌ 2NH₃

Exothermic in the forward direction.

  • NH₃ is removed

  • N₂ is added

  • H₂ is added

  • Pressure is increased (4:2)

  • Temperature decreased

  • NH₃ is added

  • N₂ is removed

  • H₂ is removed

  • Pressure is decreased

  • higher temperature

  • Fe Catalyst added

  • Shifts equilibrium to the left

  • Shifts equilibrium to the right

  • No change
