Ammonia is oxidized with air to form nitric oxide in the first step of the manufacture of nitric acid. Two principal reactions occur. 4 NH3 + 50₂4 NO + 6H₂O 2 NH3 +0₂ N₂ + 3 H₂O 100 mol NH3(g)/min 25°C, 8 bars 900 mol air/min 0.21 0₂ 0.79 N₂ 150°C, 8 bars - Q (kJ/min) AĤ-904.7 kJ/mol AĤº = -633.1 kJ/mol Product gas: 700°C, 8 bars 90 mol NO/min 150 mol H₂O(g)/min 716 mol N₂/min 69 mol O₂/min Calculate the heat transferred to or from the reactor, taking atomic species as references for enthalpy calculations. (See Example 9.5-2.) AH = - 4896.1 kJ/min. 4896.1 kJ/min heat removed
