Gce Model Questions Vol1 2019 Chemistry Question 45
Practice objective / multiple choice question 45 from the 2019 Gce Model Questions Vol1 Chemistry examination.
A galvanic cell is set up with the half‑cells \(\mathrm{Cu^{2+} + 2e^- \rightarrow Cu}\) (standard potential \(E^{\circ}=+0.34\ \text{V}\)) and \(\mathrm{Fe^{2+} + 2e^- \rightarrow Fe}\) (standard potential \(E^{\circ}= -0.44\ \text{V}\)). The cell operates at \(298\ \text{K}\) and the observed electromotive force is \(0.75\ \text{V}\). If the concentration of \(\mathrm{Cu^{2+}}\) is \(0.10\ \text{M}\), calculate the concentration of \(\mathrm{Fe^{2+}}\) in the cell. Use the Nernst equation with base‑10 logarithms.
