Chapter 12, Problem 12.62SP

Interpretation Introduction

Interpretation:

For the given first order reaction, the value of rate constant has to be calculated at $\text{25}{}^{\text{o}}\text{C}$.

Concept introduction:

Half-life time:

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

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