AP Chemistry
9.9 Cell Potential and Free Energy
A student refers to the following table of standard reduction potentials at \(298\text{ K}\) to evaluate the relative reactivity of several chemical species.
Based on the data in the table, which of the following correctly ranks the species from strongest to weakest oxidizing agent?
| Half-reaction | \(E^\circ\text{ (V)}\) |
|---|---|
| \(\text{Ag}^+\text{(aq)} + \text{e}^- \rightarrow \text{Ag(s)}\) | \(+0.80\) |
| \(\text{Cu}^{2+}\text{(aq)} + 2\,\text{e}^- \rightarrow \text{Cu(s)}\) | \(+0.34\) |
| \(\text{Ni}^{2+}\text{(aq)} + 2\,\text{e}^- \rightarrow \text{Ni(s)}\) | \(-0.25\) |
