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//10^(th)` value?

A

`3837 sec^(-1)`

B

`0.03837 sec^(-1)`

C

`0.0387 min^(-1)`

D

`0.3837 sec^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
`t = 2.303/K log a/(a-x)` If a=1 then `(a-x) = 1/10`
