Chapter 20, Problem 20.66E

Interpretation Introduction

Interpretation:

The value of the rate constant at $100°\text{C}$ for the given reaction is to be predicted.

Concept introduction:

The Arrhenius equation gives the temperature dependence of reaction rates.

$k=A{e}^{-E_A/RT}$

Where,

• $k$ is the rate constant.

• $A$ is the pre-exponential factor.

• $E_A$ is the activation energy.

• $R$ is the gas constant and its value is $8.314\text{J}\cdot {\text{K}}^{-1}\cdot {\text{mol}}^{-1}$.

• $T$ is the temperature.

The pre-exponential factor is also known as the frequency factor or the steric factor.
