Question

The galvanic cell illustrated above generates a potential of +1.10V. For the construction of a second galvanic cell (not shown), only one modification was made: the Cu electrode has double the mass of the Cu electrode in the first cell. Which of the following correctly compares the initial E° for the second cell to that of first cell at 298K, and why?

Answer 1

Answer:

The initial  E°  for the second cell is the same as for the first cell.

Explanation:

Because the overall chemical reaction that occurs in the cell does not change.

Answer 2

The first galvanic cell generated the cell potential of +1.10 V. The second galvanic cell generates the same cell potential because the overall cell reaction remains the same.

What is a galvanic cell?

The galvanic cell is given as the electrochemical cell that generates the exchange of chemical and electrical energy.

The cell potential is described as the rate of reaction with the difference in the potential of the cathode and the anode.

The reduction and the oxidation potential are governed by the number of electrons transferred in the chemical reaction.

In the second galvanic cell, the number of electrons transferred from the copper electrode will be equivalent to the first electrode, as the chemical reaction is the same. Thus, the cell potential of the second galvanic cell will be the same as the first cell.
