A cell in which a spontaneous redox reaction takes place is called a:
AGalvanic cell
BElectrolytic cell
CConcentration cell
DPhotovoltaic cell
Answer & Solution
Correct answer: A. Galvanic cell
1. Devices that separate a redox reaction into two half-cells are electrochemical cells.
2. They divide into two families by whether the reaction runs on its own.
3. Those in which a spontaneous redox reaction takes place are called galvanic cells, or voltaic cells.
4. An electrolytic cell has to be driven by an applied voltage instead.
