Chapter 16, Problem 16.1IA

Interpretation Introduction

Interpretation:

Whether the expression, $E_{\text{a}}=R{T}^2\left(\text{d}\ln k_{\text{r}}/\text{d}T\right)$, may be used to extract the activation energy from the equation, $\eta ={\eta }_0{\text{e}}^{E_{\text{a}}/RT}$, has to be confirmed.  The temperature dependence of the activation energy has to be determined.  The activation energy has to be plotted as a function of temperature.  An explanation for the temperature dependence of $E_{\text{a}}$ has to be stated.

Concept introduction:

The standard entropy of activation is the change in entropy when the reactants change from their initial state to the activated complex or transition state. It determines the molecularity and rate of reaction.
