उत्तर
We know that `"t"_(1/2) = 0.693/"k"`
`"t"_(1/2) = 0.693/(1.54 xx 10^-3 "s"^-1)` = 450 s

The rate of a first order reaction is 0.04 mol litre-1 s-1 at 10 minutes and 0.03 mol litre-1 sec-1 at 20 minutes after initiation. The half-life of the reaction is ______ min.
Assertion (A): The half-life of a reaction is the time in which the concentration of the reactant is reduced to one-half of its initial concentration.
Reason (R): In first-order kinetics, when the concentration of reactant is doubled, its half-life is doubled.
