### Galvanic Cell

When you are given a problem in regards to a galvanic cell, can you assume that the cell potential of the reaction is always positive?

Yes, I believe so. The solutions manual states this when explaining problem 6L.7 from the seventh edition.

Yes, the cell potential has to be positive because the galvanic cell is converting chemical energy to electrical energy. A positive cell potential is related to a spontaneous reaction as well.

### Re: Galvanic Cell

It would be safe to assume that the cell potential is positive in a galvanic cell when doing problems in the textbook or on a test because there would not be much to prove or calculate if the cell potential was negative.
