Ammonia is oxidized with air to form nitric oxide in the first step to produce nitric acid.  The reaction occurs in a well insulated continuous reactor based on the stoichiometry:  

4 NH₃ + 5 O₂ → 4 NO + 6 H₂O

If 100 mol min^-1 of ammonia at 25°C, 8 bar is fed to the reactor and air at 150°C, 8 bar is used with 50% excess, if the reaction goes to completion:

a. Find the composition of the product.

b. Perform an energy balance in the system writing down relevant equations.

c. An estimate for the outlet temperature of the reactor.
