What will be the half-life of the first order reaction for which the value of rate constant is `200 s^(-1)`?

A

`3.46 xx 10^(-2) s`

B

`3.46 xx 10^(-3) s`

C

`4.26 xx 10^(-2) s`

D

`4.26 xx 10^(-3) s`

Text Solution

Verified by Experts

The correct Answer is:
B
`t_(1//2) = (0.693)/(k) = (0.693)/(200) = 3.46 xx 10^(-3) s`
