Neco 2017 Chemistry Question 29
Practice objective / multiple choice question 29 from the 2017 Neco Chemistry examination.
The standard reduction potentials are: \( \mathrm{Fe^{3+} + e^{-} \rightarrow Fe^{2+}} \), \( E^{\circ}=+0.77\ \text{V} \); and \( \mathrm{Ce^{4+} + e^{-} \rightarrow Ce^{3+}} \), \( E^{\circ}=+1.61\ \text{V} \). When an aqueous solution of \( \mathrm{Fe^{2+}} \) is mixed with an aqueous solution of \( \mathrm{Ce^{4+}} \), a redox reaction occurs. Write the overall balanced equation, calculate the standard cell potential (\( E^{\circ}_{\text{cell}} \)) and the equilibrium constant \( K \) at 25 °C (assume \( n = 1 \) for the overall reaction).
