Neco Model Questions Vol1 2023 Chemistry Question 24
Practice objective / multiple choice question 24 from the 2023 Neco Model Questions Vol1 Chemistry examination.
Consider the galvanic cell: \(\text{Zn(s)}\,|\,\text{Zn}^{2+}(0.010\ \text{M})\,||\,\text{Cu}^{2+}(0.10\ \text{M})\,|\,\text{Cu(s)}\). Standard reduction potentials are \(E^{\circ}_{\text{Zn}^{2+}/\text{Zn}} = -0.76\ \text{V}\) and \(E^{\circ}_{\text{Cu}^{2+}/\text{Cu}} = +0.34\ \text{V}\). (a) Calculate the standard cell potential \(E^{\circ}_{\text{cell}}\). (b) Determine the cell potential at 25 °C using the Nernst equation. (c) If the cell is operated as an electrolytic cell, what minimum external voltage is required to drive the non‑spontaneous reaction?
