# A student refers to the following table of standard reduction potentials at \(298\text{ K}\) to evaluate the relative reactivity of several chemical species.

| Half-reaction | \(E^\circ\text{ (V)}\) |
|—|—|
| \(\text{Ag}^+\text{(aq)} + \text{e}^- \rightarrow \text{Ag(s)}\) | \(+0.80\) |
| \(\text{Cu}^{2+}\text{(aq)} + 2\,\text{e}^- \rightarrow \text{Cu(s)}\) | \(+0.34\) |
| \(\text{Ni}^{2+}\text{(aq)} + 2\,\text{e}^- \rightarrow \text{Ni(s)}\) | \(-0.25\) |

Based on the data in the table, which of the following correctly ranks the species from strongest to weakest oxidizing agent?

A student refers to the following table of standard reduction potentials at \(298\text{ K}\) to evaluate the relative reactivity of several chemical species.

| Half-reaction | \(E^\circ\text{ (V)}\) |
|---|---|
| \(\text{Ag}^+\text{(aq)} + \text{e}^- \rightarrow \text{Ag(s)}\) | \(+0.80\) |
| \(\text{Cu}^{2+}\text{(aq)} + 2\,\text{e}^- \rightarrow \text{Cu(s)}\) | \(+0.34\) |
| \(\text{Ni}^{2+}\text{(aq)} + 2\,\text{e}^- \rightarrow \text{Ni(s)}\) | \(-0.25\) |

Based on the data in the table, which of the following correctly ranks the species from strongest to weakest oxidizing agent?

- **A.** \(\text{Ag(s)} > \text{Cu(s)} > \text{Ni(s)}\)
- **B.** \(\text{Ag}^+\text{(aq)} > \text{Cu}^{2+}\text{(aq)} > \text{Ni}^{2+}\text{(aq)}\)
- **C.** \(\text{Ni}^{2+}\text{(aq)} > \text{Cu}^{2+}\text{(aq)} > \text{Ag}^+\text{(aq)}\)
- **D.** \(\text{Ni(s)} > \text{Cu(s)} > \text{Ag(s)}\)
