WHICH IS THE BEST FUEL - ETHANOL OR PROPANOL? OBJECTIVE: To determine which alcohol, out of ethanol and propanol, is the better fuel. By calculating the enthalpy change of combustion for ethanol and propanol I will find how much energy is released per mole of each alcohol. To do this I will completely combust the alcohols in air, so I can then calculate how much energy is released per gram of alcohol and compare these results. BACKGROUND When establishing which alcohol is best to use as a fuel we must first consider the qualities that a good fuel must have. Some examples of these qualities are: The amount of energy released. The speed at which a fuel releases its energy - which needs to fairly high. Its' octane rating - The higher the octane number the more the fuel exhibits greater resistance to preignition. This is based on a scale from 0 (heptane)...
