STANDARD Chemistry Electrochemical Cells MCQ Question
An electrochemical cell can behave like an electrolytic cell when
E₀cell = 0
E₀cell > E₀ext
E₀ext > E₀cell
E₀cell = E₀ext
Correct Answer
Detailed Explanation
An electrochemical cell behaves like an electrolytic cell when the external potential applied is greater than the cell potential, reversing the spontaneous reaction.
