Chapter 15, Problem 104AE

(a)

Interpretation Introduction

Interpretation:

The concentration of A₂ after 3.00 min should be calculated.

Concept Introduction:

Integrated rate law for a second order reaction,

  $\frac{1}{{\left[\text{A}\right]}_t}=kt+\frac{1}{{\left[\text{A}\right]}_0}$

[A]_t − concentration of A at time t

[A]₀ − initial concentration of A

k − rate constant

t − time

(b)

Interpretation Introduction

Interpretation:

The value of k₂ should be calculated.

Concept Introduction:

Integrated rate law for a second order reaction,

  $\frac{1}{{\left[\text{A}\right]}_t}=kt+\frac{1}{{\left[\text{A}\right]}_0}$

[A]_t − concentration of A at time t

[A]₀ − initial concentration of A

k − rate constant

t − time

(c)

Interpretation Introduction

Interpretation:

The half-life for the experiment involving A should be calculated.

Concept Introduction:

Half-life of a second order reaction can be calculated by,

  $t_{1/2}=\frac{1}{k{\left[\text{A}\right]}_0}$

k − rate constant

[A]₀ − initial concentration of A.
