Nitric acid is made commercially from nitric oxide. Nitric oxide is produced by the gas-phase oxidation of ammonia. 4NH3+502 >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 O₂ (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
