A constant-volume tank contains a mixture of 1 kmol of benzene (C ₆ H ₆ ) gas and 30 percent excess air at 25?C and 1 atm. The contents of the tank are now ignited, and all the hydrogen in the fuel burns to H ₂ O but only 92 percent of the carbon burns to CO ₂ , the remaining 8 percent fonning CO. If the final temperature in the tank is 1000 K, determine the heat transfer from the combustion chamber during this process.
