Waec Model Questions Vol1 2020 Chemistry Question 4
Practice objective / multiple choice question 4 from the 2020 Waec Model Questions Vol1 Chemistry examination.
Consider a galvanic cell: Zn(s) | Zn²⁺ (0.010 M) || Cu²⁺ (0.10 M) | Cu(s). Standard electrode potentials are E°(Zn²⁺/Zn) = -0.76 V and E°(Cu²⁺/Cu) = +0.34 V. (a) Calculate the cell potential at 25 °C using the Nernst equation. (b) If the cell delivers a constant current of 0.250 A for 2.00 h, how many grams of copper are deposited on the cathode?
