In the Deacon process for the manufacture of chlorine, HCl and O2 react to form Cl2 and H2O. Sufficient air (21.0 mole % O2, 79.0% N2) is fed to provide 35.0% excess oxygen and the fractional conversion of HCl is 75.0%. a. Calculate the mole fractions of the product stream components using atomic species balances in your calculation. N2 O2 Cl2 HCl H2O b. Again calculate the mole fractions of the product stream components using the extent of reaction and stoichiometric coefficients in the calculation for the conditions of 40.0% excess oxygen and a fractional conversion of HCl of 80.0%. N2
