Chapter 3, Problem 3.10P

(a)

Interpretation Introduction

Interpretation:

The activation energy for the given reaction has to be calculated.

Concept Introduction:

The minimum amount of energy that is needed to initiate a chemical reaction is termed as activation energy. It is expressed as $E$. The unit of activation energy is $\text{J/mol}$.

The activation energy is used in the Arrhenius equation. The expression for the same is,

    $k={\text{Ae}}^{-E/\text{R}T}$

(b)

Interpretation Introduction

Interpretation:

The value of the frequency factor of the given reaction is to be calculated.

Concept introduction:

The frequency factor $\text{A}$ is used in the Arrhenius equation. The expression for the same is,

    $k={\text{Ae}}^{-E/\text{R}T}$

The frequency factor, $\text{A}$, is defined as the pre-exponential factor that is used to show the relation between the temperature and rate constant of the chemical reaction.

(c)

Interpretation Introduction

Interpretation:

The value of rate constant as a function of temperature by using equation $\left(\text{S3}-5\right)$ and $T_0=27°\text{C}$ is to be calculated.

Concept introduction:

The rate of any chemical reaction is dependent upon its rate constant $k$. The rate constant of any reaction is dependent upon the temperature of the reaction. The expression for the dependency of rate constant on temperature is,

    $k={\text{Ae}}^{-E/\text{R}T}$
