If we move down the electrochemical series:

Explanation

Moving down the electrochemical series, the reduction potential will increase. The electrochemical series, also known as the activity series, is a list of elements or compounds arranged in order of their reduction potentials. Reduction potential is a measure of the tendency of a species to gain electrons and undergo reduction in a redox reaction. In the electrochemical series, elements or compounds higher up in the series have more negative reduction potentials, indicating a lower tendency to gain electrons and be reduced. Conversely, elements or compounds lower down in the series have more positive reduction potentials, indicating a greater tendency to gain electrons and be reduced. As you move down the electrochemical series, the reduction potential increase because the species are mire likely to accept electrons and be reduced. This is due to factors such as increasing atomic size, decreasing electronegativity, and decreasing ionization energy as you move down the series. In summary, as you move down the electrochemical series, the reduction potential increase, indicating an increasing tendency to undergo reduction.
