(a) NH3 and O₂ are fed to a reactor at 25°C and at the rates of 100 mol/s and 200 mol/s respectively. The ammonia is completely consumed, according to the following reaction equation at 1 atm: 4 NH3(g) + 5 O₂ (g) → 4 NO(g) + 6 H₂O (g) In order to maintain the product gas at a temperature of 300°C, 19,700 kW of heat must be removed from the reactor. (i) Calculate the standard heat of reaction for the above reaction equation. (ii) Calculate the standard heat of reaction for NH3(g) + 5/4 O₂ (g) → NO(g) + 3/2 H₂O (g) Specific enthalpies of gas (referenced to 25°C and 1 atm): O₂ (g) at 300°C, 1 atm: 8.470 kJ/mol NO (g) at 300°C, 1 atm: 8.453 kJ/mol H₂O(g) at 300°C. 1 atm: 9.570 kJ/mol
