Chapter 20, Problem 95IAE

Interpretation Introduction

(a)

Interpretation:

The reaction order for following reactions is to be determined.

$\begin{array}{l}\text{NO(g)}\to \frac{\text{1}}{\text{2}}{\text{N}}_{\text{2}}\text{(g)+}\frac{\text{1}}{\text{2}}{\text{O}}_{\text{2}}{\text{(g) k}}_1=25.7{\text{ s}}^{-1}\\ \text{NO(g)}\to \frac{\text{1}}{\text{2}}{\text{N}}_{\text{2}}\text{O(g)+}\frac{\text{1}}{\text{4}}{\text{O}}_{\text{2}}{\text{(g) k}}_2=18.2{\text{ s}}^{-1}\end{array}$

Concept introduction:

• Parallel reactions are those in which a reactant A undergoes one of the two irreversible first order reactions to form either product B or product C.
