Chapter 18, Problem 11E

Interpretation Introduction

Interpretation:

The signs of the activation energies for the forward and reverse reactions, assuming that the reaction given in Figure $\text{18-3}$ is reversible, are to be compared. Whether the signs of the activation energies are positive, negative or the same are to be predicted. Whether the sign is positive or negative, if it is the same for both the forward and reverse reactions, is to be predicted.

Concept introduction:

According to collision theory, reactant molecules collide with proper orientation and sufficient energy to form products. Activation energy can be defined as the amount of energy that is required to convert reactant molecules into products.
