The rate constant for a first order reaction is 60 s–1. How much time will it take to reduce the initial concentration of the reactant to its 1/16th value?

Answer :


Order of the reaction = 1

Let, Initial concentration [R]°= x

Final concentration [R] = x/16

Rate constant k = 60 s-1

We know, time

Solving, we get t = 4.6 × 10-2s
