Chapter 14, Problem 14.87SP

Interpretation Introduction

Interpretation:

It needs to be explained that two reactions with same activation energy and same temperature, rate differs by a factor of 10.

Concept introduction:

The activation energy is the minimum amount of energy that is needed to change the reactant molecule to product molecules. The relation between activation energy, rate constant and temperature can be written as:

${\text{k = A e}}^{\text{-Ea/RT}}$

Here:

• k = rate constant
• A = Frequency constant
• R = gas constant
• T = Temperature
