Chapter 13, Problem 13.74QE

(a)

Interpretation Introduction

Interpretation:

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

    ${\text{ NO}}_{\text{(g)}}{\text{ + NO}}_{\text{3 (g) }}\stackrel{}{\to }{\text{ 2NO}}_{\text{2(g)}}$

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.
