Question

Electrolytic cell is a device

• A. in which a non-spontaneous chemical reaction is carried out at the expense of electrical energy
• B. in which a spontaneous chemical reaction is carried out to generate electrical energy
• C. in which applied opposite potential is less than the cell potential
• D. Both (a) and (c)

Answer 1

Answer: (A)

When $E_{\text {ext }}>E$ generated, the cell behaves like an electrolytic cell. In this cell a non-spontaneous reaction is carried out at the expense of electrical energy.
