Bromine (br2) is produced by reacting hbr with o2, with water as a byproduct. the o2 is part of an air (21 mol % o2, 79 mol % n2) feed stream that is flowing sufficiently fast to provide 25% excess oxygen ("excess" has a precise meaning in process analysis: in this case there is 25% more oxygen than the amount needed to completely react with the limiting reactant). the fractional conversion of hbr is 78%.
a) show the degree of freedom analysis. be as specific as possible about labeling the unknowns and completely write out all of the independent equations.
b) calculate the composition (mole fractions) of the product stream.
