Unit of rate and rate constant are same for:
Correct answer: D. Zero order reaction
- A. First order reaction
- B. Second order reaction
- C. Third order reaction
- D. Zero order reaction
Explanation
In the zero-order reaction, the rate is independent of the concentration of reactants and hence, the units of rate and rate constant become equal which is mol/L/time. So, the correct answer is option D.

About Order of Reaction
Reaction order shows how the rate depends on the concentration of each reactant, as expressed in the rate law. Coverage includes zero, first and second-order reactions, integrated rate equations, half-life, units of rate constants and the distinction between overall order and molecularity.
