Chapter 9.4, Problem 9.4BFP

Interpretation Introduction

Interpretation:

The value of ${\text{ΔH}}_{\text{rxn}}^{\text{o}}$ has to be calculated using bond energies.

Concept Introduction:

Simple method of calculating$\Delta H_{rxn}^o$:

1. 1. Break all the reactant bonds to obtain individual atoms.
2. 2. Use the atoms to form all the product bonds.
3. 3. Add the bond energies, with appropriate signs, to obtain the enthalpy of reaction.
