Consider the following diagram and use it to answer the question below
Which of the following half reaction equations represent the reaction at the cathode
- A\(^{3+_{(aq)}}\)+3e\(^{-}\) \(\rightarrow\) A\(_{(s)}\)
-
B\(^{2+_{(aq)}}\)+2e\(^{-}\) \(\rightarrow\) B\(_{(s)}\)
- A\(_{(s)}\) \(\rightarrow\) \(^{3+_{(aq)}}\)+3e\(^{-}\)
- B\(_{(s)}\) \(\rightarrow\) B\(^{2+_{(aq)}}\) + 2e\(^{-}\)
