Question
Pure liquid octane (C8H18; d = 0.702 g/mL) is used as the fuel
in a test of a new automobile drive train.
(a) How much energy (in kJ) is released by complete combustion
of the octane in a 20.4-gal fuel tank to gases (ΔH°rxn = -5.45×103 kJ/mol)?
(b) The energy delivered to the wheels at 65 mph is 5.5×104 kJ/h.
Assuming all the energy is transferred to the wheels, what is the cruising range (in km) of the car on a full tank?
(c) If the actual cruising range is 455 miles, explain your answer to part (b).
