1. Wet air containing 4.0 mole% water vapor at 76°F and 14.8 psia is passed through a column of calcium chloride pellets. The pellets absorb 97% of the water and none of the other constituents of the air. The column packing was initially dry and had a mass of 3.40 kg. Following 5.0 hours of operation, the pellets are reweighed and found to have a mass of 3.52 kg. Calculate the molar ?ow rate (mol/h) of the feed gas and the mole fraction of water vapor in the product gas.
2. Ammonia is burned with oxygen to form nitric oxide (NO) and water.
a) Calculate the ratio (lbmole O2 react/lbmole NO formed).
b) If ammonia is fed to a continuous reactor at a rate of 100 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.
