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. The fractional conversion of HBr is 78%.
A) Show the degree of freedom analysis for each of the three methods: molecular species balances, atomic species balances, and extent of reaction. 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 using molecular species balances
