Chapter 16.4, Problem 16.5BFP

(a)

Interpretation Introduction

Interpretation:

The rate constant for the decomposition reaction has to be identified.

Concept introduction:

Rate law or rate equation: The relationship between the reactant concentrations and reaction rate is expressed by an equation.

$\begin{array}{l}\text{aA + bB}\to x\text{X}\\ \\ {\text{Rate of reaction = k [A]}}^{\text{m}}{\text{[B]}}^{\text{n}}\end{array}$

First order reaction: $\text{ln}\frac{{\left[\text{A}\right]}_{\text{0}}}{{\left[\text{A}\right]}_{\text{t}}}\text{ = kt}\text{.}$

(b)

Interpretation Introduction

Interpretation:

The time required for the decomposition reaction has to be identified.

Concept introduction:

Rate law or rate equation: The relationship between the reactant concentrations and reaction rate is expressed by an equation.

$\begin{array}{l}\text{aA + bB}\to x\text{X}\\ \\ {\text{Rate of reaction = k [A]}}^{\text{m}}{\text{[B]}}^{\text{n}}\end{array}$

First order reaction: $\text{ln}\frac{{\left[\text{A}\right]}_{\text{0}}}{{\left[\text{A}\right]}_{\text{t}}}\text{ = kt}\text{.}$
