Example 4:

Ammonia (NH₃) gas decomposes over platinum catalyst to nitrogen gas (N₂) and hydrogen gas (H₂). The chemical reaction is as follows:

The reaction follows zero order kinetics. Therefore the rate law is rate r = k[NH₃]^o

For a zero order reaction the concentration versus time profile is linear and the rate of reaction versus time has the profile.
