Calculate the Equilibrium Constant for the Following Reaction at 25

question 22

Multiple Choice

Calculate the equilibrium constant for the following reaction at 25 °C, 2 IO₃^-(aq) + 5 Hg( ) + 12 H⁺(aq) → I₂(s) + 5 Hg²⁺(aq) + 6 H₂O( )
The standard reduction potentials are as follows:
IO₃^-(aq) + 6 H⁺(aq) + 5 e^- → I₂(s) + 3 H₂O( )
E° = +1.20 V
Hg²⁺(aq) + 2 e^- → Hg( )
E° = +0.86 V
