Chapter 19.5, Problem 6PPA

Interpretation Introduction

Interpretation:

The half-life of the reaction should be calculated.

Concept introduction:

Half-life, $t_{1/2}$:

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

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