Zero orderMediumQuestion 720007
Question
For a zero-order reaction, the rate constant k has units:
- Amol L⁻¹ s⁻¹Correct
- Bs⁻¹
- CL mol⁻¹ s⁻¹
- DL² mol⁻² s⁻¹
Correct answer
mol L⁻¹ s⁻¹
Explanation
Zero order: r = k. Units of r = mol L⁻¹ s⁻¹ = units of k. For first order: k in s⁻¹; for second order: k in L mol⁻¹ s⁻¹.
