Which statements about a galvanic cell are correct?
Hints
- Three follow from the thermodynamics; one confuses intensive with extensive.
- A flat battery is a cell that has reached equilibrium.
Show the answer
- A. A flat battery is one whose reaction has run all the way to equilibrium
- B. A positive cell potential indicates a spontaneous reaction
- D. Electrons flow through the external circuit from anode to cathode
Why
A positive potential means a negative , electrons leave the oxidising anode, and the potential decays to zero as climbs toward . Potential is intensive and never scales with the equation.
