Gce Model Questions Vol1 2024 Chemistry Question 30
Practice objective / multiple choice question 30 from the 2024 Gce Model Questions Vol1 Chemistry examination.
In an electrolytic cell a copper electrode is immersed in a \(0.010\ \text{M}\) \(\text{CuSO}_4\) solution. A constant current of \(0.50\ \text{A}\) is passed for \(2.00\ \text{h}\). (a) Assuming 100 % current efficiency, calculate the mass of copper deposited on the cathode. (b) If the cathode overpotential is \(0.10\ \text{V}\) and the anode overpotential is \(0.05\ \text{V}\), determine the minimum cell voltage required to sustain the electrolysis. Use the standard reduction potential \(E^\circ_{\text{Cu}^{2+}/\text{Cu}} = +0.34\ \text{V}\) and assume the temperature is \(298\ \text{K}\).
