Use the following bond energies (in kJ mol-') to calculate a value for the standard enthalpy change of this reaction: Е(С-C) %3 +347 ii Е(С-Н) — +410 iii Е(С-0) %3 +336 iv E(O=0) = +496 %3D V E(C=0) = +805 vi E(0–H) = +465 %3D The standard enthalpy change of combustion of ethanol is -1367.3 kJ molH. Suggest why this value differs from the value obtained using bond energies.
