Q. The equilibrium reaction that is not influenced by volume change at constant temperature is
A) $H_{2}(g) + I_{2}(g) \rightleftharpoons 2HI(g)$
B) $N_{2}(g) + 3H_{2}(g) \rightleftharpoons 2NH_{3}(g)$
C) $N_{2}O_{4}(g) \rightleftharpoons 2NO_{2}(g)$
D) $2NO(g) + O_{2} \rightleftharpoons 2NO_{2}(g)$
Explanation
(a)
$H_{2}(g) + I_{2}(g) \rightleftharpoons 2HI(g)$
Here, $\mathrm{\Delta}n = 2 - 2 = 0$
Hence, this equilibrium reaction is not influenced by volume change at constant temperature.
