The enthalpy change for the given reaction should be determined using the bond dissociation enthalpies. Concept Introduction: Bond dissociation enthalpy: Bond energy or more correctly the bond dissociation enthalpy is the enthalpy change when breaking a bond in a molecule with the reactant and products in the gas phase. The process of breaking bonds in a molecule is always endothermic, so Δ r H for bond breaking is always positive.

Solutions

Chapter 8, Problem 87GQ
Interpretation Introduction

Interpretation: The enthalpy change for the given reaction should be determined using the bond dissociation enthalpies.

Concept Introduction:

Bond dissociation enthalpy:

Bond energy or more correctly the bond dissociation enthalpy is the enthalpy change when breaking a bond in a molecule with the reactant and products in the gas phase.

The process of breaking bonds in a molecule is always endothermic, so ΔrH for bond breaking is always positive.
