Units for the rate constant k of the zero order rate equation are

Options

A. `L^2 mol^(-2) sec^(-1)`
B. `L mol^(-1) sec^(-1)`
C. `sec^(-1)`
D. `mol L^(-1) sec^(1)`

Answer

D

Explanation

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)`
