Benzene gas (C6H6) at 25oC is burned during a steady flow combustion process with 90% theoretical air that enters the combustion chamber at 25oC. All the hydrogen in the fuel burns to H2O, but part of the carbon burns to CO. If the products leave at 1500 K, determine (a) the mole fraction of the CO in the products (in percent) and (b) the heat transfer (q-) from the combustion chamber during this process per unit mole of fuel.
