Question
If the accompanying drawing of an electrochemical cell represents an iron-nickel cell, use the partial activity series included to select the half-reaction represented by the right side of the cell.

Partial Activity Series:
- Zn → Zn²⁺ + 2e⁻
- Fe → Fe²⁺ + 2e⁻
- Co → Co²⁺ + 2e⁻
- Ni → Ni²⁺ + 2e⁻
- Cu → Cu²⁺ + 2e⁻

Options:
- Fe → Fe²⁺ + 2e⁻
- Ni → Ni²⁺ + 2e⁻
- Fe²⁺ + 2e⁻ → Fe
- Ni²⁺ + 2e⁻ → Ni

**Selected Answer:** Ni²⁺ + 2e⁻ → Ni

**Description of Diagram:**
The diagram illustrates an electrochemical cell setup. Two beakers are connected with a salt bridge. Each beaker contains a solution and an electrode immersed in it. An arrow indicates electron flow connecting the electrodes, powering a light bulb, which signifies that the cell is generating electricity. The two metals shown in the cell are iron and nickel, corresponding to a standard iron-nickel cell.
