The correct answer is:
CHECK THE SOLUTION.

Given, chemical reaction is

At very high pressure, reaction become independent of concentration of ammonia i.e., zero order reaction.
Hence, Rate

Rate
Rate of reaction Rate constant
Rate of decomposition of ammonia will remain constant until ammonia disappears completely.
Since, formation of ammonia is a reversible process further increase in pressure will change the rate of reaction. According to Le-Chatelier principle increase in pressure will favour in backward reaction.
