Answer» c... You can see in the balanced reaction that the Ammonia and Oxygen required are in the ratio 4:5 Thus 4 moles of Ammonia requires 5 moles of oxygen. 4 NH3 ≈ 5O21 NH3 ≈ 1.25 O2 Now we have oxygen in less quantity as compared to Ammonia, thus Oxygen is the limiting reagent. So we balance to suit Oxygen. 4NH3 ≈ 5O20.8 NH3 ≈ 1 O2 Thus the reaction becomes0.8 NH3 + 1 O2 → 0.8 NO + 1.2 H2O Thus all of the oxygen is used. 0.2 moles of NH3 are unused and we acquire 0.8 moles of NO and 1.2 moles of H2O.

You can see in the balanced reaction that the Ammonia and Oxygen required are in the ratio 4:5

Thus 4 moles of Ammonia requires 5 moles of oxygen.

4 NH3 ≈ 5O21 NH3 ≈ 1.25 O2

Now we have oxygen in less quantity as compared to Ammonia, thus Oxygen is the limiting reagent. So we balance to suit Oxygen.

4NH3 ≈ 5O20.8 NH3 ≈ 1 O2

Thus the reaction becomes0.8 NH3 + 1 O2 → 0.8 NO + 1.2 H2O

Thus all of the oxygen is used. 0.2 moles of NH3 are unused and we acquire 0.8 moles of NO and 1.2 moles of H2O.
