Concept explainers
Interpretation: The age of artifact is to be determined.
Concept Introduction:
The rate constant (k) of the reaction is determined by:
The integrated rate law is as follows:
Here, N is the amount of sample left after time T and
As radioactivity is a first-order process, the rate of decay is directly proportional to the number of nuclei in the sample. Thus, the initial rate of decay
Substitute the value of
