The unit of the rate constant (\(k\)) for a zero-order reaction depends on the rate law. For a zero-order reaction, the rate is independent of the concentration of the reactants and is given by:
\[
\text{Rate} = k
\]
The unit of the rate is typically **concentration per unit time** (e.g., \(\text{mol L}^{-1} \text{s}^{-1}\)). Since the rate constant \(k\) equals the rate in a zero-order reaction, its unit is:
\[
k = \text{mol L}^{-1} \text{s}^{-1}
\]
