For a first order reaction with rate constant 'k' and initial concentration 'a', the half-life period is given by

A

`(l n2)/(k)`

B

`(1)/(ka)`

C

`(0.693)/(k)`

D

`(3)/(2ka^(2))`

Text Solution

Verified by Experts

The correct Answer is:
A, C
`t_(1//2)=(l n2)/(k)=(2.303log2)/(k)=(2.303xx0.3010)/(k)`
`=(0.693)/(k)`
