Q. For which of the following reactions, does the equilibrium constant depend on the units of concentration?
A) $NO(g) \rightleftharpoons \frac{1}{2}N_{2}(g) + \frac{1}{2}O_{2}(g)$
B) $Zn(s) + Cu^{2 +}(aq) \rightleftharpoons Cu(s) + Zn^{2 +}(aq)$
C) $COCl_{2}(g) \rightleftharpoons CO(g) + Cl_{2}(g)$
D) $C_{2}H_{5}OH(l) + CH_{3}COOH(l) \rightleftharpoons CH_{3}COOC_{2}H_{5}(l) + H_{2}O(l)$
Explanation
(c)
$\mathrm{\Delta}ng = 1$ for this change, so the equilibrium constant depends on the units of concentration
