Chapter 13, Problem 13.73QE

(a)

Interpretation Introduction

Interpretation:

The rate law and molecularity of for the given elementary reaction has to be written.

    $\text{HCl }\stackrel{}{\to }\text{H + Cl}$

Concept Introduction:

The rate law is an equation which provides the relationship between rate of a reaction and the concentration of reactants in a reaction.

Molecularity tells about the number of reactant participated in a reaction.

• If only one reactant participated in a reaction then the reaction is called unimolecular reaction and its molecularity is 1.
• If only two reactants participated in a reaction then the reaction is called bimolecular reaction and its molecularity is 2.
• If only three reactants participated in a reaction then the reaction is called termolecular reaction and its molecularity is 3.

(b)

Interpretation Introduction

Interpretation:

The rate law and molecularity of for the given elementary reaction has to be written.

    ${\text{ H}}_{\text{2}}\text{ + Cl }\stackrel{}{\to }\text{ HCl + H}$

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

The rate law and molecularity of for the given elementary reaction has to be written.

    ${\text{ 2NO}}_{\text{2}}\stackrel{}{\to }{\text{ N}}_{\text{2}}{\text{O}}_{\text{4}}$

Concept Introduction:

Refer to part (a).
