Neco Model Questions Vol1 2022 Chemistry Question 50
Practice objective / multiple choice question 50 from the 2022 Neco Model Questions Vol1 Chemistry examination.
A galvanic cell is constructed as follows: Fe(s) | Fe²⁺ (0.020\,M) || Cu²⁺ (0.050\,M) | Cu(s). Standard reduction potentials are \(E^\circ_{\text{Fe}^{2+}/\text{Fe}} = -0.44\)\,V and \(E^\circ_{\text{Cu}^{2+}/\text{Cu}} = +0.34\)\,V. (a) Write the overall cell reaction. (b) Calculate the cell potential at 25\,°C using the Nernst equation. (c) If the cell operates until the Fe²⁺ concentration reaches 0.050\,M, how many grams of copper are deposited on the copper electrode? Assume each half‑cell contains 1.00\,L of solution.
