Concept explainers
(a)
Interpretation:
The percentage of I-131 disintegrated needs to be determined.
Concept introduction:
All the radioactive reactions are first order reactions. For first order reaction, the relation between rate constant, k and half-life time is as follows:
Also, the integrated rate expression can be written as follows:
Here, t is time required to decrease the amount of substance from
