By seeing the unit of k, we can say that this is 1st order reaction.
Given:
k = 4.47*10^-2 s-1
use relation between rate constant and half life of 1st order reaction
t1/2 = (ln 2) / k
= 0.693/(k)
= 0.693/(4.47*10^-2)
= 15.5 s
Answer: 15.5 s

For a first-order reaction, the half-life is constant. It depends only on the rate constant k k and not on the reactant concentration. It is expressed as t1/2=0.693k t 1 / 2 = 0.693 k For a second-order reaction, the half-life depends on the rate constant and the concentration of the reactant and so is expressed as t1/2=1k[A]0. A certain first-order reaction (A→products A → p r o d u c t s ) has a rate constant of 9.30×10−3...
