Ethanol, CHOH, burns completely in oxygen according to the equation:
.
Using the bond energies below, calculate the enthalpy change, , for this reaction.
C–C: 350 kJ/mol
C–O: 360 kJ/mol
C–H: 410 kJ/mol
O–H: 460 kJ/mol
O=O: 500 kJ/mol
C=O: 800 kJ/mol
Assume ethanol has 5 C–H bonds, 1 C–C bond, 1 C–O bond and 1 O–H bond.
