Ammonia is burned to form nitric oxide in the following reaction:
p NH$_3$ + q O$_2$ $\rightarrow$ r NO + s H$_2$O
Balance the above reaction to determine the stoichiometric coefficients p, q, r and s.
Calculate the ratio (lb-mole O react/lb-mole NO formed).
Case I: If ammonia is fed to a continuous reactor at a rate of 100.0 kmol/h, what oxygen feed rate (kmol/h) would correspond to 45.0% excess O$_2$? What would be the product composition in mol %?
Case II: If 50.0 kg of ammonia and 100.0 kg of oxygen are fed to a batch reactor, determine a) the limiting reactant, b) the percentage by which the other reactant is in excess, c) the extent of reaction and d) mass composition of the product components in kg if the reaction proceeds to completion.
