Question:medium
For a first-order reaction, the unit of rate constant is: ____.
For a first-order reaction, the unit of rate constant is: ____.
Show Hint
To quickly find the units for any order, remember that the units of Rate are always mol L⁻¹ s⁻¹. For first order, Rate = $k$[A], so $k$ must simply be "per time" to cancel out the concentration units.

- mol L⁻¹ s⁻¹
- s⁻¹
- L mol⁻¹ s⁻¹
- mol² L⁻² s⁻¹
