Chapter 16, Problem 16.160MP

Interpretation Introduction

(a)

Interpretation:

Therate law of reaction and the value of rate constant with its unit needs to be determined.

Concept introduction:

A mathematical relationship is obtained by comparing the reaction rates with reactant concentrations or partial pressures of reactants. The addition of the concentration term exponents of rate law equation is expressed by the reaction order.

The reaction's rate law may be determined by the initial rates method.

For general reaction $\text{A+B}\to \text{C}$, rate constant is given by:

$\text{r = k}{\left[\text{A}\right]}^{\text{x}}{\left[\text{B}\right]}^{\text{y}}$

Interpretation Introduction

(b)

Interpretation:

The value of rate constant ${\text{k}}_2$ for the second step needs to be determined.
