Chapter 7, Problem 48P

The rate of the reaction

In the first order in ${{\text{(CH}}_{\text{3}}\text{)}}_{\text{3}}\text{CCl}$ and first order in ${\text{NaSCH}}_{\text{2}}{\text{CH}}_{\text{3}}$. Give the symbol $\text{(E1}\text{and}\text{E2)}$ for the most reasonable mechanism, and use curved arrows the flow of electrons.
