Chapter 22, Problem 92IE

Interpretation Introduction

Interpretation: The average $\text{Xe}-\text{F}$ bond enthalpy in ${\text{XeF}}_{\text{2}}$ , ${\text{XeF}}_4$ and ${\text{XeF}}_6$ and the significance of the trend in their quantities is to be determined.

Concept introduction: The bond enthalpy $\left(\text{Δ}{H}^{\text{o}}\right)$ is calculated by the formula,

$\Delta H^{\text{o}}{}_{\text{rxn}}=\Delta H^{\text{o}}{}_{\text{product}}-\text{Δ}{H}^{\text{o}}{}_{\text{reactant}}$

To determine: The average $\text{Xe}-\text{F}$ bond enthalpy in ${\text{XeF}}_{\text{2}}$ , ${\text{XeF}}_4$ and ${\text{XeF}}_6$ and the significance of the trend in their quantities.
