Chapter 14, Problem 84IL

(a)

Interpretation Introduction

Interpretation: The molarity of each of the elementary reactions should be determined.

Concept introduction:

Molecularity: It is defined as the number of reacting species involved in a chemical reaction.

(b)

Interpretation Introduction

Interpretation: Rate equation of the reaction should be determined and decided whether it agrees with the given mechanism.

Concept introduction:

Rate law or rate equation: Rate law:

It is generally the rate equation that consists of the reaction rate with the concentration or the pressures of the reactants and constant parameters.

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

Rate constant, k: The rate constant for a chemical reaction is the proportionality term in the chemical reaction rate law which gives the relationship between the rate and the concentration of the reactant present in the chemical reaction.

(c)

Interpretation Introduction

Interpretation: The concentration of the product should be determined after $\text{5}\text{.0}\text{minutes}$.

Concept introduction:

Rate law or rate equation: Rate law:

It is generally the rate equation that consists of the reaction rate with the concentration or the pressures of the reactants and constant parameters.

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

The integrated rate law for the first order is as follows:

  $\begin{array}{l}k=\frac{1}{t}\ln \frac{\left[A_0\right]}{\left[A\right]}\\ \text{Where,}\\ \left[{\text{A}}_{\text{0}}\right]\text{= initial}\text{concentration}\\ t=time\\ \left[\text{A}\right]=concentrationaftertimet\end{array}$
