Question

For which specific order of a chemical reaction are the fundamental units of the specific rate constant ($k$) mathematically identical to the units of the overall rate of the reaction?

Answer: A

💡 Solution & Explanation

The rate of reaction always has units of $\text{mol L}^{-1}\text{s}^{-1}$. The rate constant $k$ has units of $(\text{mol L}^{-1})^{1-n} \text{s}^{-1}$. When order $n=0$, the units of $k$ become exactly $\text{mol L}^{-1}\text{s}^{-1}$, perfectly matching the reaction rate.
