A first order reaction is found to have ...

A first order reaction is found to have a rate constant, `k=5.5 xx10^(-14)s^(-1).` Find the half- life of the reaction.

Text Solution

Verified by Experts

Half-life for a first order reaction is
`t_(1//2)=(0.693)/(k)`
`t_(1//2)=(0.693)/(5.5xx10^(-14)S^(-1))=1.26xx10^(13)S`
