Chapter 25.8, Problem 1.2ACP

Interpretation Introduction

Interpretation: To determine the ratio of the rates of decomposition of the two major isotopes namely, uranium–235 and uranium–238

Concept introduction:

Half–life period: It is the time required for the concentration of a substance to reduce to the one-half of its initial concentration.

The half–life period for first order reaction is as follows:

  $\begin{array}{l}{\text{t}}_{\text{1/2}}\text{=}\frac{0.693}{\text{k}}\\ \text{Where,}\\ \text{k = Rate constant}\\ {\text{t}}_{\text{1/2}}\text{= half-life}\end{array}$
