Ethylene (C2H4) at 25oC and 1 atm is burned with 300% excess air at 25oC and 1 atm. Assuming that this reaction takes place adiabatically at 25oC and that the products leave at 25oC and 1 atm. Determine the irreversibility of the process per kg of fuel. Use the PG mixture model. Assume cp to be uniform at 1.005 kg/kJ K.
