Chapter 14, Problem 14.120SP

Interpretation Introduction

(a)

Interpretation:

The chemical equation for the overall reaction needs to be determined.

Concept introduction:

Two reactions are given in the question. To get the overall reaction both the reactions are added. The equation that is obtained after summation of two equations is the overall equation.

Interpretation Introduction

(b)

Interpretation:

The catalyst and the reaction intermediate for the reaction needs to be identified.

Concept introduction:

A catalyst is a substance that speeds up the reaction although it does not consumed in the reaction. It lowers the activation energy of the reaction that results the product formation easier. In this way catalyst speeds up reaction.

Interpretation Introduction

(c)

Interpretation:

Whether the rate of overall reaction affected if $\text{HCl}$ is added to the solution or not needs to be explained.

Concept introduction:

The rate constant in chemical kinetics relates molar concentration of reactant to reaction rate. It is known as reaction rate coefficient and denoted by symbol k.
