A galvanic cell has an electrical potential of 1.1V. If an opposing potential of 1.1V is applied to this cell, what will happen to the cell reaction and current flowing through the cell?

A galvanic cell has an electrical potential of 1.1V if an opposing potential of 1.1V is applied to this cell.

If the opposing potential equals the electric potential of the galvanic cell, then the flow of electrons stops.

When the reaction stops altogether, and no current flows through the cell.

Any further increase in the external potential again starts the reaction but in the opposite direction.
