1. identify which one can be an electron donor and which one can be an electron acceptor. 2. Then build two possible oxidation reduction reactions using any of your four redox couples. Note that each reaction has to have both an electron donor and an electron acceptor.

3. Lastly, calculate the number of electrons transferred for each of the reactions that you built.

NO₃^-/NO₂^-

S⁰/ H₂S

NO/N₂O

fumarate/succinate

Consider the following redox reaction:

acetoacetate + 2H⁺ + 2Fe²⁺ --> Î²-hydroxybutyrate + 2Fe³⁺

Answer each of the following questions:

(A) Write each of the two half-reactions that comprise this overall reaction; clearly indicate which half-reaction is a reduction & which half-reaction is an oxidation.

(B) For the forward reaction (as written above), which reactant is the electron donor? which is the electron acceptor?

(D) Based on your calculated value for Part (C), explain why this redox reaction occurs spontaneously in either the forward or reverse direction (clearly indicate which). Be sure to frame your explanation in terms of relative electron affinity.
