Chapter 13, Problem 13.76QE

(a)

Interpretation Introduction

Interpretation:

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

    ${\text{ NO + NO}}_{\text{2}}\text{Cl }\stackrel{}{\to }{\text{ NO}}_{\text{2 }}\text{+ NOCl}$

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.

    ${\text{ NO}}_{\text{2}}{\text{ + SO}}_{\text{2}}\stackrel{}{\to }{\text{ NO + SO}}_{\text{3}}$

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.

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

Concept Introduction:

Refer to part (a).
