Chapter 6, Problem 44P

Consider the following reaction: ${\text{CH}}_{\text{4}}+\text{Cl}\cdot \to \cdot {\text{CH}}_{\text{3}}+\text{HCl}$.

a. Use curved arrows to show the movement of electrons.

b. Calculate $\Delta H°$ using the bond dissociation energies in table 6.2.

c. Draw an energy diagram assuming that $E_{\text{a}}=16\text{kJ}/\text{mol}$.

d. What is $E_{\text{a}}$ for the reverse reaction $\left(\cdot {\text{CH}}_3+\text{HCl}\to {\text{CH}}_4+\text{Cl}\cdot \right)$?
