For a first order reaction, units of rate constant are

A

`"time"^(-1)`

B

`"L mol"^(-1)s^(-1)`

C

`"mol L"^(-1) s^(-1)`

D

`"mol L"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
Rate `k ("conc.")^(n)`
`k = ("Rate")/(("conc.")^(n))`
For a first order reaction, `n=1`
`:. k=("Rate")/(("conc."))=("mol L"^(-1)"s"^(-1))/("mol L"^(-1))`
`=s^(-1) or ("time")^(-1)`
