TED-ED: The chemical reaction that feeds the world - Daniel D. Dulek

The video discusses the significance of the Haber process, a chemical reaction that converts nitrogen and hydrogen into ammonia, which is crucial for fertilizer production. This process enables food production for billions of people. The video explains chemical equilibrium and Le Chatelier's principle, which are essential for understanding how the Haber process works. It also highlights the environmental impact of ammonia production and the need for a sustainable alternative.

What is the primary purpose of the Haber process?

• To generate hydrogen fuel

• To synthesize plastics

• To create ammonia for fertilizers

• To produce electricity

Why can't crops directly use nitrogen from the air?

• It is too dense

• It is too cold

• It has strong triple bonds

• It is too light

What happens when a chemical reaction reaches equilibrium?

• The reaction stops completely

• The forward and reverse reactions occur at the same rate

• The reaction speeds up

• The reaction only produces reactants

How does increasing pressure affect the Haber process?

• It slows down the reaction

• It favors the production of ammonia

• It decreases the temperature

• It stops the reaction

What principle helps in shifting the equilibrium in the Haber process?

• Charles's Law

• Le Chatelier's Principle

• Avogadro's Law

• Boyle's Law

What percentage of ammonia is used in fertilizer production?

• 50%

• 60%

• 80%

• 70%

What is a major environmental concern associated with the Haber process?

• Excessive carbon emissions

• Air pollution from ammonia

• Nitrogen compounds in water supplies

• Depletion of water resources
