Two galvanic cells with two different chemical reactions are given. The value of E ° for both the cells is to be calculated. Concept introduction The galvanic cell converts chemical energy into electrical energy while the electrolytic cell converts electrical energy into chemical energy. The species at anode undergoes oxidation while the species at cathode undergoes reduction and the electrons generated at the anode are transferred through wire to the cathode.

Write the reagents required to bring about each reaction next to the arrows shown.
Next, record any regiochemistry or stereochemistry considerations relevant to the
reaction. You should also record any key aspects of the mechanism, such as forma-
tion of an important intermediate, as a helpful reminder. You may want to keep
track of all reactions that make carbon-carbon bonds, because these help you build
large molecules from smaller fragments. This especially applies to the reactions in…
