The rate constant for a first order reac...

The rate constant for a first order reaction is `80 s^-1`. How much time will it take to reduce the concentration of the reactants to `1/18^(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) [log_10 = 1]`
`t = 2.303/60 log"" ([A]_010)/([A]_0)`
t = 0.038
`t = 3.8 xx 10^(-2)s`
