TEMA 14. BALANCES SIMULTÁNEOS DE MATERIA Y ENERGÍA | EJERCICIO 14.1. COMBUSTIÓN DE BENCENO

Benzene is burned with excess air to ensure complete combustion. The hydrocarbon and air enter at 25°C and 1 atm, and the combustion gases exit at 290°C. If the Orsat analysis of the combustion gases (in % by volume) is as follows: CO2: 12.37%; O2: 6.19%; N2: 81.44%, calculate: a) The excess air used, relative to the theoretically required amount. b) The heat released per kg of hydrocarbon burned.
