Question:
The unit of rate constant for a zero order reaction is:
L²mol⁻¹s⁻¹
mol L⁻¹s⁻¹
L mol⁻¹s⁻¹
s⁻¹
Solution:
The rate law expression for the zero order reaction is Rate = k[A]⁰
Rate has units of molL⁻¹sec⁻¹ = k × (molL⁻¹)⁰
Unit of k = mol L⁻¹sec⁻¹
The unit of rate constant for a zero order reaction is molL⁻¹s⁻¹.
