Answer:
0.25 moles of N₂
Explanation:
The number of moles of NH₃ produced is 0.50.
The given reaction is shown below
N ₂ ( g ) + 3 H ₂ ( g ) → 2 N H ₃ (g )
It is clear from the reaction that;
2 moles of N H ₃ are produced when 1 mole of N₂ react.
Therefore, 1 mole of N H ₃ is produced when 0.5 mole N ₂
Thus, 0.5 moles of N H ₃ are produced when 0.5 × 0.5 moles of N ₂ react.
Hence, 0.5 moles of N H ₃are produced when 0.25 moles of N ₂ react.
Therefore, the number of moles of N₂ reacted to form 0.5 moles of N H ₃ is 0.25
