A new fuel, which has a molar mass of 112 g/mol and a density of 0.712 g/ml, is used in an automobile test run. The delta H of combustion for the fuel is -5.55x10^3 kJ/mol. The automobile has a 20.6 gal fuel tank. The energy delivered by the combustion of the fuel is 5.62 x 10^4 kJ/h at 60.0 mph.
What is the cruising range (in miles) of the automobile on a full tank, assuming all the energy is transferred to the wheels?
If the actual cruising range is 732 km, what is the efficiency of the engine?
How can I calculate the equilbrium constant and delta G and S given the enthalpy per mol of reaction and the final number of moles at equilbrium?
