For a first order reaction, units of rate constant are

A

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

B

`s^-1`

C

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

D

`L^(2) "mol"^(-2) s^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
For nth order reaction ,
the units of rate constant = (mol `L^(-1))^(1 - n) s^-1`
(where , n = order of reaction )
`therefore` For 1st order reaction , the units of rate constant = (mol `L^(-1))^(1-1) s^(-1)`
`= s^(-1)`
