Multipart Problems: 13.(20 points) Ammonia is oxidized to form nitric oxide in the following reaction: 4NH3 + 502 + 4NO + 6H2O a) Calculate the ratio of moles of O2 consumed to moles of NO formed. (moles 02 / moles NO.) b) If ammonia were fed to a continuous reactor at a rate of 100.0 kmol/hr, what molar oxygen (O2) feed rate (kmol/hr) would correspond to 30.0% excess? c) If 55.0 kg of ammonia and 80.0 kg of oxygen are fed to a batch reactor, determine the following: i) the limiting reactant ii) the amount in moles by which the other reactant is in excess iii) the extent of the reaction (molar) iv) the mass of NO produced (kg) if the reaction proceeds to completion
