At high pressure, decomposition of NH₃ in the presence of the Pt catalyst and 1130 K is a zero order reaction.

Identify incorrect statement about the reaction from the following?

The rate of reaction depends on the concentration of ammonia.

The half-life of the reaction increases with an increase in the initial concentration of ammonia. 

The rate of reaction is equal to the rate constant of the reaction.

The rate of decomposition of ammonia will remain constant until the ammonia disappears completely.
