A variable, opposite external potential (Eext) is applied to the cell ZnZn2+(1M)Cu2+(1M)Cu of potential 1.1 V. When Eext <1.1V and Eext >1.1V respectively, electrons flow from:

detailed solution

Correct option is A

The cell will function as a galvanic cell if Eext<1.1V,  at which point electrons will flow from the anode to the cathode.

Eext >1.1V, causes electrons to flow from cathode to anode, causing the cell to function as an electrolytic cell.
