Estimate the enthalpy change for the combustion of one mole of ethanol (C2H5OH) using average bond dissociation enthalpies (in KJ/mol) for C-H: 413, O-H: 463, C-O: 358, C-C: 154, C=O: 122, and O=O: 498. Then use the estimate to calculate the heat of formation of ethanol from the heats of formation (in KJ/mol) of CO2: 394, and H2O: 242.© BrainMass Inc. brainmass.com December 15, 2020, 9:54 pm ad1c9bdddf
See the attached file for the response. I do want to point out that your values for C-C and C=O seem to be ...
The solution estimates the enthalpy change for combustion.
