"Zero order reaction must be multi-step"- Explain
Zero order reactions means the rate of the reaction does not depend on the reactant concentration. But the reactants are converted to product. So this reaction takes place in multiple steps.
For ex.,
Decomposition of HI on gold surface
HI ----> 1/2 H2 + 1/2 I2
