3) Ammonia gas enters the reactor of a nitric acid plant mixed with 30% more dry air than is required for the complete conversion of the ammonia to nitric oxide and water vapour. If the gases enter the reactor at 348.15K, if conversion is 80%, if no side reactions occur, and if the reactor operates adiabatically, what is the temperature of the gases leaving the reactor? Assume ideal gases and take CP=A. 4NH3(g)+5O2(g)4NO(g)+6H2O(g) (ANS: 2560.2K )
