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 :

Given:


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
