Chapter 17, Problem 9CR

Interpretation Introduction

Interpretation:

A graph for the progress of a reaction illustrating the activation energy for the reaction is to be sketched. The term “activation energy” is to be defined. The reason behind the explanation of an increase in temperature for a reaction affects the number of collisions that possess energy greater than ${\text{E}}_{\text{a}}$ is to be stated. Whether an increase in temperature changes ${\text{E}}_{\text{a}}$ or not is to be predicted. The explanation for a catalyst speed up a reaction is to be stated. Whether a catalyst change ${\text{E}}_{\text{a}}$ value or not is to be predicted.

Concept Introduction:

The conversion of reactants into products relies on various factors such as temperature, catalyst and activation energy. The reaction will occur at a faster rate, if the activation energy is low. The high value of activation energy implies that high energy is required to convert the reactants into products, whereas a low value of activation energy suggests that low energy is needed to convert the reactants into products.
