The rate constant for a first order reac...

The rate constant for a first order reaction in `60S^(-1)`. How much time will it take to reduce the concentration of the reactant to `1/(20^(th))` of its initial value ?

Text Solution

Verified by Experts

`t = (2.303)/K "log " ([A]_0)/([A])` (First Order Equation)
`k=60 S^(-1) " " [A] = ([A]_0)/(10) " " [log10=1] `
`t = (2.303)/(60) " log" ([A]_010)/([A]_0)`
`t - 0.038 `
`t = 3.8 xx 10^(-2)s`
