(a)
Interpretation:
The reason for radon-222 to not simply decay as fast as it is produced without reaching to the maximum concentration needs to be explained.
Concept introduction:
All the radioactive decay reactions follow first order kinetics. The expression for rate law can be represented as follows:
Here,
(b)
Interpretation:
An expression for change in number of atoms of radon-222 related to number of atoms of radium-226 and decay constant of parent and daughter needs to be determined.
Concept introduction:
All the radioactive decay reactions follow first order kinetics. The expression for rate law can be represented as follows:
Here,
(c)
Interpretation:
The time taken for the amount of radon-222 to reach a maximum value needs to be determined.
Concept introduction:
All the radioactive decay reactions follow first order kinetics. The expression for rate law can be represented as follows:
Here,
