# A galvanic cell is constructed as shown in the diagram below.

| Half-Reaction | \(E^\circ\text{ (V)}\) |
|—|—|
| \(\text{Zn}^{2+}\text{(aq)} + 2\text{e}^- \rightarrow \text{Zn(s)}\) | \(-0.76\) |
| \(\text{Cu}^{2+}\text{(aq)} + 2\text{e}^- \rightarrow \text{Cu(s)}\) | \(+0.34\) |

When the cell operates spontaneously at \(298\text{ K}\), which of the following correctly describes the movement of electrons through the external circuit and the movement of \(\text{K}^+\) cations through the salt bridge?

A galvanic cell is constructed as shown in the diagram below.

| Half-Reaction | \(E^\circ\text{ (V)}\) |
|---|---|
| \(\text{Zn}^{2+}\text{(aq)} + 2\text{e}^- \rightarrow \text{Zn(s)}\) | \(-0.76\) |
| \(\text{Cu}^{2+}\text{(aq)} + 2\text{e}^- \rightarrow \text{Cu(s)}\) | \(+0.34\) |

When the cell operates spontaneously at \(298\text{ K}\), which of the following correctly describes the movement of electrons through the external circuit and the movement of \(\text{K}^+\) cations through the salt bridge?

![A grayscale schematic diagram shows two open beakers connected by an external wire and an inverted U-tube. The left beaker contains liquid labeled 1.0 M Zn(NO3)2 and a solid vertical rectangle with solid gray fill labeled Zn(s). The right beaker contains liquid labeled 1.0 M Cu(NO3)2 and a solid vertical rectangle with diagonal hatched fill labeled Cu(s). The inverted U-tube bridges both beakers with its open ends immersed in the liquids and is labeled KNO3 salt bridge. A single line representing a wire connects the top of the Zn(s) strip to the top of the Cu(s) strip, passing through a circle labeled V centered above the beakers. No other particles, labels, text, or annotations appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787459000-13d1f1.jpg)

- **A.** Electrons flow from the \(\text{Zn}\) electrode to the \(\text{Cu}\) electrode, and \(\text{K}^+\) ions migrate toward the \(\text{Cu}^{2+}\) half-cell.
- **B.** Electrons flow from the \(\text{Zn}\) electrode to the \(\text{Cu}\) electrode, and \(\text{K}^+\) ions migrate toward the \(\text{Zn}^{2+}\) half-cell.
- **C.** Electrons flow from the \(\text{Cu}\) electrode to the \(\text{Zn}\) electrode, and \(\text{K}^+\) ions migrate toward the \(\text{Cu}^{2+}\) half-cell.
- **D.** Electrons flow from the \(\text{Cu}\) electrode to the \(\text{Zn}\) electrode, and \(\text{K}^+\) ions migrate toward the \(\text{Zn}^{2+}\) half-cell.
