Galvanic (Voltaic) and Electrolytic Cells

AP Chemistry· difficulty 3/5

Galvanic spontaneous E° > 0 Electrolytic non-spontaneous requires power

Comparing the two cells, the electrolytic one

  • A

    Has no electrodes

  • B

    Requires an external power supply (E° < 0)

  • C

    Is at equilibrium

  • D

    Generates current

Explanation

Electrolytic cells use applied current to drive non-spontaneous redox.
