Chapter 25, Problem 78SCQ

Interpretation Introduction

Interpretation: To calculate the rate constant for the radioactive isotope of uranium-238 by using first order reaction and compared with the literature value.

Concept introduction:

The rate of decay can be calculated by the following formula:

  $\frac{\text{ΔN}}{\text{Δt}}\text{= -kN}$

Here,

  K is the rate constant

  N is the number of nuclei in 1.0mg of sample (Avogadro number=$6.02\times {10}^{23}$).
