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, c) | 2. | (b, c, d) |
| 3. | (a, c, d) | 4. | (a, b, d) |
Hint: For zero order reaction rate of reaction is equal to 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.
