Question:medium

What would be the cell potential for the Galvanic cell which is represented by the electrochemical reaction: \[ 2 \text{Cr(s)} + 3 \text{Fe}^{2+} (0.02M) \rightarrow 2 \text{Cr}^{3+} (0.2M) + 3 \text{Fe} \] \[ E^{0}_{\text{Fe}^{2+}/\text{Fe}} = -0.42 \, \text{V}, \quad E^{0}_{\text{Cr}^{3+}/\text{Cr}} = -0.72 \, \text{V} \]

Show Hint

To calculate the cell potential under non-standard conditions, use the Nernst equation. Ensure you correctly assign oxidation and reduction reactions, and use the correct concentrations of the products and reactants.
