10.4 The Haber process and the use of NPK fertilizers

• The Haber process reaction is reversible.


  True
• The Haber process is essential for global food supply.


  True
• Match the nutrient in NPK fertilizers with its role:

  Nitrogen ↔️ Stimulates leaf growth

  Phosphorus ↔️ Aids root development

  Potassium ↔️ Increases disease resistance
• Arrange the conditions in the Haber process based on their significance for ammonia production:

  1️⃣ High pressure

  2️⃣ Iron catalyst

  3️⃣ Temperature of 450°C
• Why is the Haber process crucial for global food supply?

  Converts nitrogen into usable nutrients
• NPK fertilizers contain the three major nutrients that plants need: nitrogen, phosphorus, and potassium
• What process provides the nitrogen needed for NPK fertilizers?

  Haber process
• What is the role of phosphorus in plant growth?

  Aids root development
• The Haber process equation describes the production of ammonia from nitrogen and hydrogen
• What pressure is used in the Haber process to shift the equilibrium to the right?

  200 atmospheres
• Match the nutrient in NPK fertilizers with its importance:

  Phosphorus (P) ↔️ Aids root development

  Potassium (K) ↔️ Increases disease resistance
• Order the importance of nutrients in NPK fertilizers for plant growth:

  1️⃣ Nitrogen (N)

  2️⃣ Phosphorus (P)

  3️⃣ Potassium (K)
• What is the chemical equation for the Haber process?

  $N_{2} +$$3H_{2} \rightleftharpoons 2NH_{3}$
• NPK fertilizers contain nitrogen, phosphorus, and potassium
• The Haber process provides nitrogen for NPK fertilizers.


  True
• The Haber process produces large quantities of ammonia, which is a key ingredient in fertilizers
• Match the nutrient in NPK fertilizers with its importance:

  Nitrogen ↔️ Stimulates leaf growth

  Phosphorus ↔️ Aids root development

  Potassium ↔️ Increases disease resistance
• Nitrogen is essential for the production of chlorophyll, which gives plants their vibrant green appearance
• The Haber process reaction is reversible, meaning it can proceed in both directions
• In the Haber process, a temperature of 450°C is used because lower temperatures favor the formation of ammonia
• In NPK fertilizers, nitrogen stimulates leaf and stem growth
• NPK fertilizers ensure that crops receive the primary nutrients they require.


  True
• Which greenhouse gas is released during the Haber process?

  Nitrous oxide
• High temperature speeds up the Haber process reaction, but lower temperatures favor the formation of ammonia
• Match the condition in the Haber process with its significance:

  Temperature ↔️ Speeds up reaction

  Pressure ↔️ Shifts equilibrium

  Catalyst ↔️ Accelerates reaction rate
• Potassium in NPK fertilizers supports water regulation
• What type of catalyst is used in the Haber process?

  Iron catalyst
• The Haber process creates nitrogen-based fertilizers that dramatically increase crop yields.

  True
• What is the chemical formula of nitrogen in NPK fertilizers?

  NH₄NO₃
• Nitrogen is a key component of chlorophyll, which is essential for photosynthesis.


  True
• Arrange the Haber process equation components into their correct order:

  1️⃣ N₂

  2️⃣ 3H₂

  3️⃣ 2NH₃
• The Haber process reaction is reversible.


  True
• Why is the Haber process essential for modern agriculture?

  Produces nitrogen fertilizers
• Why is nitrogen essential for plant growth?

  Component of chlorophyll
• Excess fertilizer runoff in waterways causes algal blooms
