Determine the enthalpy of the products of ‘ideal’ combustion (i.e., no dissociation), resulting from the combustion of an isooctane-air mixture for an equivalence ratio of 0.7. The products are at 1000 K and 1 atm. Express your result using the following three bases: per kmol-of-fuel, per kg-of-fuel, and per kg-of-product. Hint: You should be able to derive these from atom-conversation considerations.
