# A student constructs a galvanic cell under standard conditions (
\(298\text{ K}\), \(1.0\text{ M}\) solutions) using two beakers connected by a salt bridge and an external wire with a voltmeter.

Beaker 1 contains a strip of \(\text{Zn(s)}\) immersed in \(1.0\text{ M }\text{Zn(NO}_3)_2\text{(aq)}\).

Beaker 2 contains an inert \(\text{Pt(s)}\) electrode immersed in an equimolar solution containing both \(1.0\text{ M }\text{Fe(NO}_3)_2\text{(aq)}\) and \(1.0\text{ M }\text{Fe(NO}_3)_3\text{(aq)}\).

The relevant standard reduction potentials at \(298\text{ K}\) are given below:

\[\text{Fe}^{3+}\text{(aq)} + \text{e}^- \rightarrow \text{Fe}^{2+}\text{(aq)} \quad E^\circ = +0.77\text{ V}\]
\[\text{Zn}^{2+}\text{(aq)} + 2\text{e}^- \rightarrow \text{Zn(s)} \quad E^\circ = -0.76\text{ V}\]

Based on the information provided, what is the standard cell potential, \(E^\circ_{\text{cell}}\), for the galvanic cell?

- **A.** \(+0.01\text{ V}\)
- **B.** \(+1.53\text{ V}\)
- **C.** \(+2.30\text{ V}\)
- **D.** \(+3.06\text{ V}\)
