CAIE A-Level Chemistry A2 24.2.9 Nernst Equation Topic Practice

Some electrode potentials are shown in Table 3.1.

Another electrochemical cell is set up using an $\mathrm{Fe}^{3+} / \mathrm{Fe}^{2+}$ electrode and an alkaline $\mathrm{ClO}^{-} / \mathrm{Cl}^{-}$ electrode.

The concentration of $\mathrm{Fe}^{3+}$ is 1000 times greater than the concentration of $\mathrm{Fe}^{2+}$ in the $\mathrm{Fe}^{3+} / \mathrm{Fe}^{2+}$ electrode. All other conditions are standard.

Use the Nernst equation to calculate the E value of the $\mathrm{Fe}^{3+} / \mathrm{Fe}^{2+}$ electrode.

Show your working.
