When 1 mole of ammonia (NH₃) reacts with 1 mole of oxygen (O₂), which of the following outcomes occurs regarding the consumption of the reactants?
| 1. | Oxygen is completely consumed. |
| 2. | Ammonia is completely consumed. |
| 3. | Both oxygen (O₂) and ammonia (NH₃) are completely consumed |
| 4. | Neither oxygen (O₂) nor ammonia (NH₃) is completely consumed. |
In the Haber process, 30 litres of dihydrogen and 30 litres of dinitrogen were taken for the reaction which yielded only 50% of the expected product. What will be the composition of a gaseous mixture under the above condition in the end:
| 1. | 20 litres of ammonia, 20 litres of nitrogen, 20 litres of hydrogen |
| 2. | 10 litres of ammonia, 25 litres nitrogen, 15 litres of hydrogen |
| 3. | 20 litres of ammonia, 10 litres of nitrogen, 30 litres of hydrogen |
| 4. | 20 litres of ammonia, 25 litres of nitrogen, 15 litres of hydrogen |
