Question

Combine the two following standard reduction potentials, and write the balanced reaction.
Which compound will be oxidized, and which will be reduced? Which compound is
considered the electron acceptor? Calculate ΔE and ΔG.
(each is given as oxidized + e- > reduced)
Acetaldehyde + 2H+ + 2e- > Ethanol Eo' = -0.197
S + 2H+ +2e- > H2S Eo' = -0.274
