The decay profiles of three radioactive ...

The decay profiles of three radioactive species A, B and C are given below :

These profiles imply that the decay constants `k_A`, `k_B` and `k_C` follow the order

A

`k_A gt k_B gt k_C`

B

`k_A gt k_C gt k_B`

C

`k_B gt k_A gt k_C`

D

`k_C gt k_A gt k_A`

Text Solution

Verified by Experts

The correct Answer is:
D
`C_t = C_0 e^(-kt)`
Hence , `K_C gt K_B gt K_A`
