Nitric acid is commercially prepared from nitric oxide, which is produced by oxidation of ammonia in the gas phase:

The feed consists of 15 mol of ammonia with air at 8.2 atm and 227 c. a) calculate the total concentration at the entrance b) What concentration is the ammonia in the inlet? c) prepare a stoichiometric table using ammonia as the calculation basis, for a constant pressure and isothermal batch system. Find  i. Later Express the C of each of the species as a function of the X. Find  i. d) Prepare a stoichiometric table using ammonia as the basis of calculation, for a constant pressure and isothermal flow system. Then express the C of each one of the species as a function of X. Find theta i, epsilon ,
