Question:
For a closed system consisting of a reaction, N\(_2\)O\(_4\) \( (g) \) \( \rightleftharpoons \) 2NO\(_2\) \( (g) \), the pressure:
For a closed system consisting of a reaction, N\(_2\)O\(_4\) \( (g) \) \( \rightleftharpoons \) 2NO\(_2\) \( (g) \), the pressure:
Show Hint
In a reaction where the number of moles of gas decreases, the pressure also decreases as the system reaches equilibrium.

- Remains constant
- Decreases
- Increases
- Becomes zero
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understand the equilibrium concept.
In this reaction, as the system approaches equilibrium, the volume decreases because the number of moles of gas decreases. This leads to a decrease in pressure.
Step 2: Conclusion. Thus, the pressure decreases as the reaction progresses.
Step 2: Conclusion. Thus, the pressure decreases as the reaction progresses.
