Chapter 10, Problem 46IP

(a)

Interpretation Introduction

Interpretation:

The temperature dependency of initiation step for radical bromination should be analyzed.

Concept introduction:

$\text{ΔG}$ (Gibbs free energy) can be identified by using formula.

General formula to calculate the Gibbs free energy is $\text{ΔG = ΔΗ –TΔS}$

$\text{ΔΗ}$ is Enthalpy, $\text{ΔS}$ is Entropy.

When the heat energy was absorbed by the system from the surrounding is called endothermic reaction

When heat energy or light energy was unconfined to the surrounding from the system is called exothermic reaction.

(b)

Interpretation Introduction

Interpretation:

The given reaction is not thermodynamically favorable at low temperature has to be explained.
