Question

The spontaneous reaction that takes place in this cell is

• A. \(\mathrm{Zn} + \mathrm{Ni} \rightarrow \mathrm{Zn^{2+}} + \mathrm{Ni^{2+}}\)
• B. \(\mathrm{Zn} + \mathrm{Ni^{2+}} \rightarrow \mathrm{Zn^{2+}} + \mathrm{Ni}\)
• C. \(\mathrm{Ni} + \mathrm{Zn^{2+}} \rightarrow \mathrm{Ni^{2+}} + \mathrm{Zn}\)
• D. \(\mathrm{Ni^{2+}} + 2\mathrm{K} \rightarrow 2\mathrm{K^+} + \mathrm{Ni}\)

Hint:

Metal with lower reduction potential acts as anode and undergoes oxidation.
