Extracted text: QUESTIONS No. 14) – 33): Nitric acid is made commercially from nitric oxide. Nitric oxide is produced by the gas-phase oxidation of ammonia. 4NH3 + 502 - 4NO + 6H20. The feed consists of 15 mol% ammonia in air at 8.2 atm and 227°C. Assume the reaction is in first order in both reactants.
