Chapter 11.3, Problem 11.4PSP

(a)

Interpretation Introduction

Interpretation:

The order of reaction with respect to $NOandC{l}_2$ has to be determined.

Concept Introduction:

The relationship between rate and initial concentration of reactant is described by rate law.  It is an experimentally determined equation and cannot be found out theoretically from the stoichiometry of the reactants and products.

  $rate=k{\left[concentrationofthereac\tan t\right]}^m$

Where, $k$ is the rate constant and $m$ is the order of the reaction.

The overall order of the reaction is the sum of the powers of the concentration terms in the rate law.

(b)

Interpretation Introduction

Interpretation:

The rate of the reaction after making the changes in the concentration of the reactant has to be explained.

Concept Introduction:
