Ammonia is burned to form nitric oxide in the following reaction: 4NH3 + 5O2 → 4NO + 6H2O
(a) Calculate the ratio (lb-mole O2 react/lb-mole NO formed).
(b) If ammonia is fed to a continuous reactor at a rate of 100.0 kmol NH3/h, what oxygen feed rate (kmol/h) would correspond to 40.0% excess O2?
(c) If 50.0 kg of ammonia and 100.0 kg of oxygen are fed to a batch reactor, determine the limiting reactant, the percentage by which the other reactant is in excess, and the extent of reaction (mol) and mass of NO produced (kg) if the reaction proceeds to completion?
