Chapter 17, Problem 17.7IA

Interpretation Introduction

Interpretation:

The photochemical chlorination of trichloromethane (${\text{CHCl}}_{\text{3}}$) in the gas to give ${\text{CCl}}_{\text{4}}$ has been found to follow the rate law ${\text{d[CCl}}_{\text{4}}\text{]/dt}\text{=}{\text{k}}_{\text{r}}{{\text{[Cl}}_{\text{2}}\text{]}}^{\text{1/2}}{\text{I}}_{\text{a}}^{\text{1/2}}$.  A mechanism has to be devised which leads to the given rate law when chlorine pressure is high.
