Which of the following is non spontaneous cell?
Correct answer: A. Electrolytic cell
- A. Electrolytic cell
- B. Galvanic cell
- C. Daniel cell
- D. Not
Explanation
An electrolytic cell requires an external electrical source to drive a non-spontaneous redox reaction, so its cell reaction does not proceed on its own. Students may choose a Daniell cell because it involves electrolysis-related electrode terminology, but a Daniell or galvanic cell generates electricity from a spontaneous reaction.

About Redox Reactions
Redox reactions involve oxidation and reduction occurring together, with electrons transferred between species or oxidation numbers changing. The topic covers assigning oxidation states, identifying oxidizing and reducing agents, balancing redox equations by oxidation number or half-reaction methods, and connecting chemical changes with galvanic and electrolytic cells.
