for the first order reaction the half life period is ( if K is rate constant and `alpha ` in initial concentration )

A

`(l n 2)/(k)`

B

`(1) /(k alpha )`

C

` (l n k) /( 2 ) `

D

`(log k)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`(l n2)/(k) =(log_(e)2)/(k)=(2.303xxlog2)/(k)=(0.693)/(k)`
