First order reaction is found to have rate constant, `k= 5.5xx 10^(-14) s^-1`. Find the half life to the reaction.

Text Solution

Verified by Experts

k=`5.5 xx 10^(-14).sec^(-1),t_(1//2)=?`
For a Ist order reaction,
`t_(1//2)=(0.693)/(k)=(0.693)/(5.5xx10^(-14)s^(-1))`
`=(6.93xx10^(13))/(5.5)s=1.26xx10^(13)s`.
