Gasohol is a mixture of ethanol and gasoline used to increase the oxygen content of fuels, and thus reduce pollutants from automobile exhaust. What is the heat of reaction for 1 kg of the mixture calculated using heat of combustion data for a fuel comprised of 10% ethanol and the rest octane? How much is the heat of reaction reduced by adding the 10% ethanol to the octane?
