Consider the reaction shown. Using your knowledge of relative acid-base strengths and equilibrium, determine what you can tell about the size of Kc for the reaction. HIO2(aq) + BrO2-(aq) ↔ IO2-(aq) + BrO2(aq)
(A) Kc = 1
(B) Kc is much greater than 1
(C) Kc is a teeny bit greater than 1
(D) Kc < 1
(E) Cannot be determined

answer: D

I really don't have a clue why? Is it because there is a stronger acid on the right? But there is no H+ on the right though. please help.

Reaction is not balanced, so there is nothing to discuss - it can't have an equiilibrium constant.

My bet is that you should have HBrO₂(aq) on the right.

Proton move?

HIO₂(aq) + BrO₂-(aq) ↔ IO₂-(aq) + HBrO₂(aq)
