A mixture of 41 moles hydrogen and 30 moles butane is burned with the 3 %excess (theoretical) air. Fractional conversions of 0.9 of the hydrogen and 0.8 of the butane are achieved; of the butane that reacts 0.46 goes to produce CO2 and the balance goes to produces the CO. Assuming that all the components in the flue gas are behaving as ideal gases, determine the total volumetric flow rate of the exhaust for a molar fuel flow rate of 100 moles/hr?
