Chapter 9, Problem 9.26P

Interpretation Introduction

Interpretation:

Combustion energy of ethanol should be determined.

Concept introduction: The energy for combustion can be determined by subtracting the enthalpy of bond formation of each product from dissociation energy of each reactant by multiplying the respective molar coefficient as follows:

$\Delta {\text{H}}_{\text{combustion}}={\displaystyle \sum \text{B}{\text{.E}}_{\text{product}}}-{\displaystyle \sum \text{B}{\text{.E}}_{\text{reactant}}}$
