Neco Model Questions Vol1 2022 Chemistry Question 22
Practice objective / multiple choice question 22 from the 2022 Neco Model Questions Vol1 Chemistry examination.
Standard reduction potentials at 25 °C are: \(\mathrm{Cu^{2+}+2e^- \rightarrow Cu(s)}\) \(E^{\circ}=+0.34\ \text{V}\) and \(\mathrm{Zn^{2+}+2e^- \rightarrow Zn(s)}\) \(E^{\circ}=-0.76\ \text{V}\). A galvanic cell is set up with a Zn(s) electrode immersed in 1.0 M ZnSO\(_4\) and a Cu(s) electrode immersed in 0.10 M CuSO\(_4\).\n(a) Write the overall cell reaction.\n(b) Calculate the cell EMF at 25 °C.\n(c) Determine the equilibrium constant \(K\) for the cell reaction.
