For the cell reaction

\mathrm{Fe} + 2\mathrm{F}{\mathrm{e}^{3 + }} = 3\mathrm{F}{\mathrm{e}^{2 + }}

, which is not possible?

View answer and explanation

Correct option: A

One cell can be constructed

Option A (One cell can be constructed) is correct because only one cell reaction is given, and therefore only one cell can be constructed based on that specific reaction.
