The rate constant for a first order reac...

The rate constant for a first order reaction is `60s^(-1)` How much time will it take to reduce the initial concentration of the reactant to its 1/6th value ?

Text Solution

Verified by Experts

Let initial concentration of the reactant be = a
`therefore` Its final concentration `=(a)/(16)`
For a first order reaction , `t=(2.303)/(k)log.(a)/(a//16)`
`thereforet=(2.303)/(60)log16=0.0462s`
