Question:
In which of the following equilibrium reaction, pressure does not influence the equilibrium at constant temperature?}
In which of the following equilibrium reaction, pressure does not influence the equilibrium at constant temperature?}
Show Hint
If total gaseous moles are equal on both sides, changing pressure does not shift equilibrium.

- \(H_2(g) + I_2(g) \rightleftharpoons 2HI(g)\)
- \(N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3(g)\)
- \(PCl_5(g) \rightleftharpoons PCl_3(g) + Cl_2(g)\)
- \(2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g)\)
- \(2N_2O_5(g) \rightleftharpoons 4NO_2(g) + O_2(g)\)

The Correct Option is A
Solution and Explanation
Pressure affects gaseous equilibrium only when the total number of moles of gas changes.
Check option (A):
\[
H_2 + I_2 \rightleftharpoons 2HI
\]
Reactant gas moles:
\[
1+1=2
\]
Product gas moles:
\[
2
\]
Since the number of gaseous moles is same on both sides, pressure has no effect.
Hence, the correct answer is: \[ \boxed{(A)} \]
Hence, the correct answer is: \[ \boxed{(A)} \]
