The time of decay for the nuclear reaction is given by `t = 5 t_(1//2)`. The relation between average life `tau` and time of decay `(t)` is given by
a. `3 tau "In" 2` b. `4 tau "In" 2` c. `5 tau "In" 2` d. `6 tau "In" 2`

A

a. `3 tau "In" 2`

B

b. `4 tau "In" 2`

C

c. `5 tau "In" 2`

D

d. `6 tau "In" 2`

Text Solution

Verified by Experts

The correct Answer is:
c. `5 tau "In" 2`
Given `t = 5t_(1//2) = 5 xx (In 2)/(K)` `[t_(1//2) = (0.693)/(K) = (In2)/(K)]`
`:.t = 5 tau "In" 2` `[tau = (1)/(K)]`
