Ten (10) kmol hr-1 of hydrogen sulfide gas is burned with the stoichiometric amount of pure oxygen in a special unit. Reactants enter as gases at 25°C and 1(atm). Products leave as two streams in equilibrium at 70°C and 1(atm): a phase of pure liquid water, and a saturated vapor stream containing H2O and SO2.
(a) What is the composition (mole fractions) of the product vapor stream?
(b) What are the rates (kmol hr-1) of the two product streams?
