Textbook 4E.5 (A)

Hi! For question 5 in the textbook chapter 4E, why is it that you do not include the C-H bond enthalpies when trying to estimate the bond enthalpy of the reaction? Thank you!

The C-H bonds in ethanol remain intact in the products (CO2 and H2O), so they are not included in the calculation of bond enthalpy changes for this reaction.

Return to “Reaction Enthalpies (e.g., Using Hess’s Law, Bond Enthalpies, Standard Enthalpies of Formation)”
