Problem 106E

Calculate  for the combustion of octane (C8H18), a component of gasoline, by using average bond energies and then calculate it using enthalpies of formation from Appendix IIB . What is the percent difference between your results? Which result would you expect to be more accurate?

Step-by-Step Solution:

Solution 106 E Step 1 of 4 First, we have to consider what is the balanced chemical equation for the combustion of octane The reaction can be written by indicating the Lewis structures for the same reactants and products Thus we can see that at the end of this reaction 7 CC bonds, 18 CH bonds and 25/2 double bonds O=O are broken, while 18 OH bonds and 16 C=O bonds are formed.
