Consider the microbial conversion of glucose to L-glutamic acid, as shown below. Assume thatinitially the bioreactor contains 200 kg of glucose, 15 kg of ammonia and 54 kg of O2.C6H1206 + NH3 +1.5 O2 →C5H9NO4+ CO2 + 3H2Oglucoseammoniaglutamic acida) Which reactant is limiting?b) What is the percentage excess of the other reactants?c) If the reaction proceeds to completion, how much of the excess reactants will be left; howmuch L-glutamic acid will be formed; and what is the extent of reaction ?d) If the reaction proceeds to a point where the conversion of the limiting reactant is 33%, howmuch of each reactant and product is present at the end, and what is the extent of reaction E ?e) If the reaction proceeds to a point where 35 kg of O2 is left, what is the fractional conversion ofglucose? What is the fractional conversion of O2? What is the extent of reaction E ?

A chemical manufacturer produces ethylene oxide by burning ethylene gas with air in the presence of catalyst. If the conditions are carefully controlled, a substantial fraction of ethylene remains unconverted and some is completely oxidized to form carbon dioxide and water. Formation of carbon monoxide is negligible. After the gases leaving the absorber is as follows: 9.6%CO2, 3.0%O2 and 6.4% ethylene. Of the ethylene entering the reactor, what percentage is converted to ethylene oxide?
