Chapter 14, Problem 14.118SP

Interpretation Introduction

(a)

Interpretation:

The overall reaction needs to be proposed.

Concept introduction:

Reaction mechanism is step by step arrangement of elementary reactions by which overall chemical change arise. A chemical mechanism is a theoretical estimation that tries to depict in detail what happens at each phase of an overall chemical reaction.

Interpretation Introduction

(b)

Interpretation:

The role of $\text{Cl}$ in given reaction mechanism needs to be explained.

Concept introduction:

A catalyst is shows up as a reactant first, and afterward as a product.

Intermediates are create in elementary step and consumed in later step of reaction mechanism. It does not take part in overall reaction.

Interpretation Introduction

(c)

Interpretation:

Whether in the given reaction mechanism $\text{ClO}$ is catalyst or a reaction intermediate.

Concept introduction:

A catalyst is shows up as a reactant first, and afterward as a product.

Intermediates are create in one step and consumed in later step of reaction mechanism. Slowest step in the mechanism is rate determining step.

Interpretation Introduction

(d)

Interpretation:

A catalyst needs to be distinguished from an intermediate.

Concept introduction:

A catalyst is shows up as a reactant first, and afterward as a product.

Intermediates are create in elementary step and consumed in later step of reaction mechanism. It does not take part in overall reaction.
