Units of rate constant of first-and zero...

Units of rate constant of first-and zero-order reactions in terms of molarity M are respectively :

A

`L^2 mol^(-2) sec^(-1)`

B

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

C

`sec^(-1)`

D

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

Text Solution

Verified by Experts

The correct Answer is:
D
For nth order reaction, unit of `k=concn.^"(n-1)" Time^(-1)`
For zero order rate equation n=o , `therefore ` units are `concn.^(-1) Time^(-1) = mol L^(-1) sec^(-1)`
