Physics Question on deccay rate
Radioactive disintegration is an example of
A
zero order reaction
B
first order reaction
C
second order reaction
D
third order reaction.
Answer
first order reaction
Explanation
Solution
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
