Galvanic cells

Do galvanic cells always have to be spontaneous?

Yes, I believe galvanic cells are always spontaneous, meaning E must be positive. Lavelle compared them to batteries, and batteries are always +E.

If you think about it, for a battery to work, the chemical rxn needs to be spontaneous.

Yes galvanic cells are always spontaneous and they convert chemical energy into electrical energy. They are essentially batteries which has a positive cell potential hence being favorable.

Yes galvanic cells are always spontaneous and produce an electric current

Yes and electrons will flow from anode to cathode! Thus, a positive cell potential for reaction to be spontaneous.

Yes! Galvanic cells are always spontaneous
