P5-8 Nitric acid is made commercially from nitric oxide. Nitric oxide is produced by the gas-phase oxidation of ammonia. 4NH, +50, 4NO+6H₂O The feed consists of 15 mol% ammonia in air at 8.2 atm and 227°C. (a) What is the total entering concentration? (b) What is the entering concentration of ammonia? (c) Set up a stoichiometric table with ammonia as your basis of calculation. (d) Express the concentration. C. for each species as functions of conversion for a constant-volume batch reactor. Express the total pressure as a func- tion of X. (e) Repeat (d) assuming the reaction is first order in NH, and half order in O, (1) Write the rate law in terms of molar flow rates (2) Write the combined rate law and mole balance solely in terms of conversion and rate law parameter for a batch reactor and for a flow reactor. (f) Calculate the reactor volume necessary to achieve 80% conversion in both a PFR and a CSTR when k=0.1 dm mol and to=2dm/s.
