NEET Chemistry Galvanic Cells MCQ Question
Which of the following statements about galvanic cells is correct?
A galvanic cell converts chemical energy into electrical energy through a spontaneous redox reaction.
Galvanic cells require an external energy source to function effectively.
The oxidation half-reaction occurs at the cathode of a galvanic cell.
Galvanic cells cannot be used to power electrical gadgets directly.
Correct Answer
Detailed Explanation
A galvanic cell indeed converts the chemical energy of a spontaneous redox reaction into electrical energy, as stated in the NCERT context. The other options are incorrect as galvanic cells do not need external energy, oxidation occurs at the anode, and they can power devices.
