Question

give one example each of zero order reaction

Answer 1

Example of zero order reaction is

Decomposition of N20 on hot platinum surface

N2O -----gives out --- N2 +1/2 O2

Answer 2

In some reactions, the rate is apparently independent of the reactant concentration. The rates of these zero-order reactions do not vary with increasing nor decreasing reactants concentrations. This means that the rate of the reaction is equal to the rate constant, k, of that reaction. This property differs from both first-order reactions and second-order reactions.
