Chapter 11, Problem 65E

Interpretation Introduction

Interpretation: The activation energy and $\Delta E$ for a reaction is given. By using these values, the activation energy for the given reverse reaction is to be calculated.

Concept introduction: A certain threshold energy which is necessary for the reaction to occur is called activation energy.

The relationship between the rate constant and activation energy is given by the Arrhenius equation,

$k=A{e}^{\frac{-E_{\text{a}}}{RT}}$

The change in energy $\left(\Delta E\right)$ is the energy difference between reactant and product. The value of $\Delta E$ is either positive or negative.

To determine: The activation energy for the given reverse reaction.
