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

Options

  1. AThe cell reaction will continue as before, and the current will flow in the same direction.
  2. BThe cell reaction will stop, and no current will flow through the cell.
  3. CThe cell reaction will reverse, and the current will flow in the opposite direction.
  4. DThe cell reaction will become faster, and the current will increase.

Correct answer

B. The cell reaction will stop, and no current will flow through the cell.

Step-by-step solution

Correct Option is : (B) The cell reaction will stop, and no current will flow through the cell.
