The first step in the Ostwald process (used to produce nitric acid) is the formation of nitric oxide from ammonia and oxygen.
4 NH3 (g) + 5 O2 (g) -------> 4 NO (g) + 6 H20 (g)
(a) What is the stoichiometric reactant ratio?
(b) How many moles of NO are formed from the reaction of 1 mol NH3?
(c) If the feed going to the reactor contains (0.430 mol NH3/mol O2), what is the limiting reactant, and the percent excess of the other reactant?
(d) What mass flow rate of NH3 is required to produce 1310 lbm of NO per day? (reactor runs 24 hrs a day)
