Radioactive disintegration is an example of
Updated On: Jul 6, 2022
- zero order reaction
- first order reaction
- second order reaction
- third order reaction.
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
rate of radioactive decay is directly proportional to the number of nuclei present in the sample. indicates that radioactive decay is constant. here from rate equation, it is clear that radioactive decay is a first-order reaction

Decay Rate
The disintegration of unstable heavy atomic nuclei into lighter, more stable, atomic nuclei, accompanied in the process by the emission of ionizing radiation (alpha particles, beta particles or gamma rays). This is a random process at the atomic level but, given a large number of similar atoms, the decay rate on average is predictable, and is usually measured by the half-life of the substance.
The equation for finding out the decay rate is given below:
