Textbook Problem

To estimate the enthalpy change for the reaction

O2(g) + 2 H2(g) → 2 H2O(g)

what bond dissociation enthalpies do you need? Outline the calculation, being careful to show correct algebraic signs.

Interpretation Introduction

Interpretation: The bond dissociation enthalpy required to estimate the enthalpy change for the given reaction should be identified.

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.

Explanation

Considering the given equation we have to find out the enthalpy change and bond dissociation enthalpies for the given reaction.

O2(g)+2H2(g)2H2O(g)

To estimate the enthalpy change, we need bond dissociation enthalpies for the following bonds:O=O,H-H and H-O
