Chapter 19.5, Problem 19.5.3SR

Interpretation Introduction

Interpretation:

The half-life of the reaction should be determined.

Concept introduction:

Half-life, ${\text{t}}_{\text{1/2}}$:

Time needed for a reactant to decrease its concentration to one half of the original concentration. Half-life of first order reaction is,

${\text{t}}_{\text{1/2}}\text{=}\frac{\text{0}\text{.693}}{\text{k}}$
