Chapter 10.2, Problem 3P

Use the data in Table $10.1$ to calculate $\text{ΔH°}$ for the iodination of methane.

$\begin{array}{cc}\text{Bond}& \text{Bond}\text{dissociation}\text{enthalpy}\text{(D)}\text{kJ/mol}\\ \text{I-I}& \text{151}\\ {\text{CH}}_{\text{3}}\text{-I}& \text{439}\\ {\text{CH}}_{\text{3}}\text{-I}& \text{238}\end{array}$
