Chapter 12, Problem 12.125CHP

Interpretation Introduction

Interpretation:

The time (in seconds) required for the pressure of ${\text{NO}}_{\text{2}}$ to reach $\text{1}\text{.3}\text{mm}\text{Hg}$ has to be calculated.

Concept introduction:

Half-life period:

It is the time required for the reactant (substrate) concentration reduces to one-half of its initial concentration.

$\begin{array}{l}{\text{t}}_{\text{1/2}}\text{=}\frac{\text{0}\text{.693}}{\text{k}}\\ \text{where,}\\ {\text{t}}_{\text{1/2}}\text{-}\text{half-life}\text{period}\\ \text{k}\text{-}\text{rate}\text{constant}\end{array}$
