Question:
Which of the following statement is not true for radioactive decay?
Which of the following statement is not true for radioactive decay?
Show Hint
The decay constant is constant for a given radioactive substance, and it does not depend on temperature.
Updated On: Mar 21, 2025
- Amount of radioactive substance remained after three half lives is \( \frac{1}{8} \)th of original amount.
- Decay constant does not depend upon temperature.
- Decay constant increases with increase in temperature.
- Half life is in 2 times of \( \frac{1}{\text{rate constant}} \).
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Decay constant is independent of temperature. The rate constant increases with temperature, but decay constant is not affected by temperature.
Thus, the correct answer is \( \boxed{(3)} \).
