Which pair of equations correctly shows the reactions occurring at the anode and at the cathode during the electrolysis of molten silver bromide?
- AAnode: $2\text{Br}^- \rightarrow \text{Br}_2 + 2e^-$; Cathode: $\text{Ag}^{2+} + 2e^- \rightarrow \text{Ag}$
- BAnode: $\text{Br}^{2-} \rightarrow \text{Br}_2 + 2e^-$; Cathode: $\text{Ag}^+ + e^- \rightarrow \text{Ag}$
- CAnode: $2\text{Br}^- \rightarrow \text{Br}_2 + 2e^-$; Cathode: $\text{Ag}^+ + e^- \rightarrow \text{Ag}$
- DAnode: $\text{Ag}^+ + e^- \rightarrow \text{Ag}$; Cathode: $2\text{Br}^- \rightarrow \text{Br}_2 + 2e^-$
