The Haber Process

• What is the Haber process used for?

  To produce ammonia (NH₃)
• What is ammonia used for in industry?

  To make fertilizers
• What two elements are needed to make ammonia?

  Nitrogen and hydrogen
• What is the chemical reaction for producing ammonia in the Haber process?

  N₂ + 3H₂ ⇌ 2NH₃ (+ heat)
• Why is the Haber process suitable for industrial scale?

  Because the reactants are inexpensive and abundant
• How is nitrogen obtained for the Haber process?

  From the air, which is 78% nitrogen
• Where does hydrogen mostly come from in the Haber process?

  From reacting methane with steam
• What role do iron catalysts play in the Haber process?

  They speed up the reaction
• What conditions are used in the Haber process?

  High temperature and high pressure
• Why is the reaction in the Haber process reversible?

  Because ammonia can decompose back into nitrogen and hydrogen
• What happens to some of the ammonia produced in the Haber process?

  It converts back into nitrogen and hydrogen
• What is the final state of the reaction in the Haber process?

  It reaches a dynamic equilibrium
• What is the state of ammonia when it is formed?

  It is a gas
• What happens to ammonia as it cools in the Haber process?

  It condenses into a liquid
• What happens to unused hydrogen and nitrogen in the Haber process?

  They are recycled
• What can the ammonia produced be used to make?

  Amonium nitrate fertilizer
• How do temperature and pressure affect the Haber process?

  Higher temperature increases rate, but lowers yield
• What is the forward reaction in the Haber process?

  N₂ and H₂ produce NH₃
• What is a trade-off in the Haber process?

  Increasing rate may decrease yield
• What is the significance of the equilibrium position in the Haber process?

  It determines the amount of ammonia produced
• What is the forward reaction in the Haber process called?

  Exothermic reaction
• How does increasing temperature affect the equilibrium in the Haber process?

  It shifts the equilibrium to the left
• What is the effect of increasing pressure in the Haber process?

  It shifts the equilibrium to the right
• What is the relationship between temperature and yield in the Haber process?

  Higher temperature decreases yield of ammonia
• What is the role of catalysts in the Haber process?

  They increase the rate of reaction
