Which of the following statement (s) differentiate between electrochemical cell and electrolytic cell? This question has multiple correct options

1. Spontaneous or non-spontaneous nature of the chemical process.
2. Chemical reactions occurring at the electrodes
3. Positive and negative nature of anode
4. Dependence on Faraday's law

Correct answer: Spontaneous or non-spontaneous nature of the chemical process.

Solution

The key distinction is that an electrochemical cell operates via a spontaneous redox reaction, while an electrolytic cell requires external electrical energy to drive a non-spontaneous reaction. The other listed features are not the primary differentiator here, since electrode reactions and anode/cathode signs depend on the cell type and setup.
