Haber process

• The Haber process is a reversible reaction used to manufacture ammonia
• Haber process:

  • Raw materials - purified nitrogen, hydrogen
  • Product - ammonia
• Conditions for Haber process:

  • 450°c
  • 200 atmospheres
• Haber conditions:

  • Exothermic reaction
  • High reaction temp gives fast rate but low yield
  • Low temp gives slow rate and fast yield
  • Moderate temp used to balance
  • High pressure gives high yield but can be dangerous and expensive
  • Low pressure gives low yield
  • Moderate pressure used
  • Iron catalyst increases rate
