Consider the Equilibrium That Exists Between Fe²⁺ and Fe³⁺ Ions

question 7

Multiple Choice

Consider the equilibrium that exists between Fe²⁺ and Fe³⁺ ions in solution.The extra electron originally on one Fe²⁺ ion can be transferred to an Fe³⁺ ion.This amounts to no net reaction because iron(II) becomes iron(III) and iron(III) becomes iron(II) .Which below about this equilibrium is true?

• A)There is no activation energy for this reaction.
• B)K = 1.
• C)K =0.
• D)There is no net reaction, so there is no value for K.
• E)The concentrations of iron(II) and iron(III) change because of the electron transfer.
