Solution: The acid HOCl (hypochlorous acid) is produced by bubbling chlorine gas through a suspension of solid mercury(II) oxide particles in liquid water according to the equation2HgO(s) + H2O(l) + 2Cl2(g) ⇌ 2

Problem

The acid HOCl (hypochlorous acid) is produced by bubbling chlorine gas through a suspension of solid mercury(II) oxide particles in liquid water according to the equation

2HgO(s) + H2O(l) + 2Cl2(g) ⇌ 2HOCl(aq) + HgO⋅HgCl 2(s)

What is the equilibrium-constant expression for this reaction?

a. K = [HOCl]/[Cl2] 2

b. K = [HOCl] 2[HgO⋅HgCl2] / [Cl2]2[H2O][HgO]2

c. K = [HOCl]2 / [Cl2]2

d. K = [HOCl]2 [Cl2]2 / [H2O]
