Open in App
Solution

Zero-order reaction:
The rate of the reaction is independent of the reactant concentration. With the progress of time, the rate of the reaction remains constant.
rate =k= constant.
The decomposition of ammonia on hot Pt surface is zero order reaction.
2NH3(g)1130K−−−PtN2(g)+3H2(g)
The decomposition of nitrous oxide to nitrogen and oxygen in presence of Pt catalyst is zero order reaction.
2N2O(g)Pt2N2(g)+O2(g)
