What is zero order reaction give one example?

In a zero-order reaction, the rate of the reaction is independent of the concentration of the reactant(s). The rate equation for a zero-order reaction is expressed as Rate = k, where ‘k’ is the rate constant. This implies that the rate is constant over time, regardless of changes in reactant concentration. An example of a zero-order reaction is the decomposition of hydrogen peroxide (H₂O₂) catalyzed by manganese dioxide (MnO₂). The rate of this reaction remains constant as the concentration of hydrogen peroxide changes, emphasizing the lack of dependence on reactant concentration in zero-order reactions.
