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?

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.

lemon juice has acid that inactivates polyphenol oxidase to prevent browning. The treatment group of apple slices sprinkled with Fruit Fresh should prevent browning. Fruit Fresh is a commercial product that contains vitamin C (also known as ascorbic acid).
