The decay constant of a radioactive element is `3 xx 10^(-6) "min"^(-1)`. Its half-life is

A

`2.31 xx 10^5` min

B

`2.31 xx 10^6` min

C

`2.31 xx 10^(-6)` min

D

`2.31 xx 10^(-7)` min

Text Solution

Verified by Experts

The correct Answer is:
A
`t_(1//2) = (0.693)/(lambda) = (0.693)/(3xx10^(-6) "min"^(-1)) = 2.31xx10^5` min
