Consider an internal combustion engine like that used in automobiles. The most common fuel used here is gasoline which is a mixture of hydrocarbons, and an octane rating is given for standardization. Therefore, we will approximate gasoline as being composed of the hydrocarbon, octane, C8H18. Another fuel that is common in racing applications is nitromethane, CH3NO2, used in top fuel dragsters. Let’s consider the combustion of each fuel with oxygen in an internal combustion engine. Let the 8-cylinder engine displacement be 500 in3 total. GOAL: Determine and compare the maximum enthalpy of reaction, ∆Ho rxn, for the combustion of both octane and nitromethane in a single cylinder of the engine. This means determine the maximum amount of fuel that can burn in the cylinder filled with 1 atm of air and the amount of heat that reaction would generate. Here are some suggested steps to guide you along. You will have to look up some data in your book or on the internet. 1. Write a balanced…
