A first order reaction is found to have a rate constant `k= 5.5 xx 10^(-14)s^(-1)`. Find 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` Show that in a first order reaction, time required for completion of 99.9% is 10 times of half-life `(t_1/2)` of the reaction.
