The unit of rate constant for a zero order reaction is -

A

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

B

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

C

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

D

`s^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
The general unit of rate constant is
`("mol.lit"^(-1))^(1-n).s^(-1)` [ where n = order of the reaction]
As, n = 0
`therefore" unit will be "("mol.lit"^(-1))^(1)s^(-1)="mol.lit"^(-1).s^(-1)`
