Chapter 9, Problem 9.30P

Interpretation Introduction

Interpretation:

The heat of combustion for gaseous ethanol in kJ/mol needs to be determined using the bond dissociation energies.

Concept introduction:

For a reaction as follows:

$\text{reactant}\to \text{product}$

The value of enthalpy of reaction can be calculated from bond dissociation energies as follows:

$\Delta H_{\text{reaction}}={\displaystyle \sum B.E_{\text{reactant}}}-{\displaystyle \sum B.E_{\text{product}}}$
