Chapter 25, Problem 25.12YT

Interpretation Introduction

Interpretation:

The diagram in figure 25-8 is to be studied, and the initiation and propagation steps are to be matched to Equation 25-18, 25-19a, 25-19b, 25-20a or 25-20b.

Concept introduction:

A free radical chain reaction involves free radicals in a cyclic sequence of steps, called propagation steps, which are responsible for converting overall reactants into overall products. An initiation step is responsible for producing the free radical that enters the propagation cycle. The termination step removes free radicals from the propagation cycle and is responsible for slowing the overall reaction.
