Final answer:
In the Haber process, nitrogen is consumed at half the rate of ammonia production while hydrogen is consumed at three times the rate of ammonia production, according to the stoichiometry of the balanced chemical equation.
Step-by-step explanation:
The Haber process is an industrial method for producing ammonia by reacting nitrogen (N₂) and hydrogen (H₂) gases:
N₂(g) + 3H₂(g) → 2NH₃(g)
According to stoichiometry of the balanced chemical equation, one mole of N₂ reacts with three moles of H₂ to form two moles of NH₃. Therefore, the rate at which nitrogen is consumed is half the rate at which ammonia is produced, and the rate at which hydrogen is consumed is three times the rate at which ammonia is produced. This is because for every 2 moles of ammonia produced, 1 mole of nitrogen and 3 moles of hydrogen are required.
