Question

An electrochemical cell can behave like an electrolytic cell when _______ .

• A. $E_{cell}=0$
• B. $E_{Cell}>E_{ext}$
• C. $E_{ext}>E_{cell}$
• D. $E_{cell}=E_{ext}$

Answer 1

Answer: (C)

When $E_{ext}>E_{cell}$, the cell starts behaving like an electrolytic cell. The external source of voltage is used to bring about a chemical reaction
