NEET Chemistry Galvanic Cells MCQ Question
Which of the following statements about galvanic and electrolytic cells is correct?
The cell potential of a galvanic cell is always positive and is measured in volts.
Electrolytic cells convert electrical energy into chemical energy without any external current.
In galvanic cells, the anode is always on the right side of the cell representation.
Electrolytic cells can undergo spontaneous reactions without any external energy source.
Correct Answer
Detailed Explanation
The cell potential of a galvanic cell is defined as the difference between the electrode potentials of the cathode and anode, and it is always positive when the cell is functioning. Electrolytic cells require external energy to drive non-spontaneous reactions, making option B incorrect. The conventional representation places the anode on the left and cathode on the right, making option C false. Electrolytic cells cannot undergo spontaneous reactions without external energy, thus option D is incorrect.
