SO 2 and O 2 mixture (66.7 mole % SO 2 and 33.3 mole % O 2 ) enters reactor B at 298 K. SO 2, SO 3 , and O 2 mixture (58.6 mole % of the mixture is SO 3 ) leaves reactor B at 811 K. A portion of the combustion gases that are used to heat the reactants in reactor B are recycled. How many moles/hr CO is required if the rate at which SO 2 enters reactor B is 2200 moles/hr? H o f , CO, gas = -109.05 kJ/mol H o f , CO2, gas = -393.51 kJ/mol H o f , SO2, gas = -296.85 kJ/mol H o f , H2O, gas = -241.83 kJ/mol H o f , SO3, gas = -395.26 kJ/mol C p (for all gases and vapors): 30 J/mol.K...
