The half-life of a first order reaction ...

The half-life of a first order reaction is 30 min.
Calculate the specific rate constant of the reaction.

Text Solution

Verified by Experts

The correct Answer is:
`k= 0.0231 min""^(-1) `

`k= ( 0.693 )/( t_(1//2)) = ( 0.693 )/(30 min)= 0.0231 min""^(-1)`
