Answer:
120 moles of NO
Step-by-step explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
4NH₃ + 6NO —> 5N₂ + 6H₂O
From the balanced equation above,
6 moles of NO reacted to produce 5 moles of N₂.
Finally, we shall determine the number of mole NO needed to produce 100 moles of N₂. This can be obtained as follow:
From the balanced equation above,
6 moles of NO reacted to produce 5 moles of N₂.
Therefore, Xmol of NO will react to produce 100 moles of N₂ i.e
Xmol of NO = (6 × 100)/5
Xmol of NO = 120 moles
Therefore, 120 moles of NO is needed for the reaction.
