Chapter 13, Problem 129AE

Interpretation Introduction

Interpretation: The value of $\Delta \text{H}$ for the following reaction should be determined using bond energies:

  ${\text{C}}_{\text{2}}{\text{H}}_{\text{4}}{\text{(g) + H}}_{\text{2}}{\text{O}}_{\text{2}}\text{(g) }\to {\text{ CH}}_2{\text{OHCH}}_2\text{OH(g)}$

Concept Introduction: The amount of energy required in order to break one mole of bond is said to be bond energy. The $\Delta \text{H}$ for a chemical reaction can be calculated using bond energies formula:

  $\Delta \text{H = }\Sigma \text{D(bonds broken) - }\Sigma \text{D(bonds formed)}$
