Chapter 20, Problem 20.99E

Interpretation Introduction

Interpretation:

The percentage change in the rate constant, when the value of $\Delta S^{\ast }$ changes from $+1\text{J}/\left(\text{mol}\cdot \text{K}\right)$ to $-1\text{J}/\left(\text{mol}\cdot \text{K}\right)$, is to be calculated.

Concept introduction:

The relationship between $\Delta S^{\ast }$ and rate constant $k$ is expressed as,

$k=\frac{ekT}{c°h}\cdot e^{-E_{\text{A}}/RT}\cdot e^{\Delta S^{\ast }/R}$
