Chapter 21, Problem 21.42P

(a)

Interpretation Introduction

Interpretation:

The heat of the reaction is to be calculated.

Concept introduction:

The heat of the reaction is calculated using following formula,

${\text{ΔH}}_{\text{Reaction}}^{\text{o}}\text{=}{\displaystyle \sum {\text{ΔH}}_{\text{Reactant}}}\text{-}{\displaystyle \sum {\text{ΔH}}_{\text{Product}}}$

(b)

Interpretation Introduction

Interpretation:

The chain propagation step is to be written and the net result of each pair of the reaction is to be shown

(C)

Interpretation Introduction

Interpretation:

The heat of the reaction is to be calculated for the propagation step.

Concept introduction:

The heat of the reaction is calculated using following formula,

${\text{ΔH}}_{\text{Reaction}}^{\text{o}}\text{=}{\displaystyle \sum {\text{ΔH}}_{\text{Reactant}}}\text{-}{\displaystyle \sum {\text{ΔH}}_{\text{Product}}}$
