| The first step in the production of nitric acid from ammonia involves the oxidation of NH3 according to the balanced reaction below: | Die eerste stap in die produksie van salpetersuur vanaf ammoniak behels die oksidasie van NH3 volgens die gebalanseerde reaksie hieronder: |
| 4 NH3(g) + 5 O2 (g) → 4 NO(g) + 6 H2O(g) | |
How much energy is evolved or absorbed as heat in the oxidation of 10.1 g of NH3 if ΔfHo[NH3(g) = -45.9 kJ.mol-1, ΔfHo[NO(g)] = 90.3 kJ.mol-1 and ΔfHo[H2O(g)] = -241.8 kJ.mol-1. | Hoeveel energie word as hitte vrygestel of geabsorbeer tydens die oksidasie van 10.1 g NH3 indien ΔfHo[NH3(g)] = -45.9 kJ.mol-1, ΔfHo[NO(g)] = 90.3 kJ.mol-1 and ΔfHo[H2O(g)] = -241.8 kJ.mol-1. |
