How many moles of n2 reacted if 0.50 mole nh3 is produced

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
