At high pressure, the following reaction is zero order:
The correct statements among the following is:
| (a) | Rate of reaction = Rate constant |
| (b) | Rate of the reaction depends on the concentration of ammonia |
| (c) | Rate of decomposition of ammonia will remain constant until ammonia disappears completely |
| (d) | Further increase in pressure will change the rate of reaction |
| 1. | a, b, and c | 2. | b, c, and d |
| 3. | a, c, and d | 4. | a, b, and d |
Hint: For a zero-order reaction the reaction is equal to the rate constant.
Given, the chemical reaction is
At very high-pressure reaction become independent of the concentration of ammonia i.e., zero-order reaction
(a) Rate of reaction = Rate constant.
(b) Rate of decomposition of ammonia will remain constant until ammonia disappears completely.
(c) Since the formation of ammonia is a reversible process further increase in pressure will change the rate of reaction. According to the Le-Chatelier principle increase in pressure will favor in backward reaction.
For zero order reaction, the rate of reaction doesnot depends the concentration of reactant.
