Academics

Assume that an internal combustion engine runs on octane, for which the enthalpy of combustion is -5512 kj mol^-1 and take the mass of 1 gallon of fuel as 3kg. Calculate the maximum height (equate the quantity of energy with the gravitational potential energy), neglecting all forms of friction, to which a car of mass1000kg can be driven on 1.00 gallon of fuel given that the engine cylinder temperature is 2000 degrees C and the exit temperature is800 degrees C?
