Waec Model Questions Vol1 2023 Chemistry Question 10
Practice objective / multiple choice question 10 from the 2023 Waec Model Questions Vol1 Chemistry examination.
A galvanic cell is constructed as follows: Zn|Zn²⁺ (0.010 M)||Cu²⁺ (0.10 M)|Cu. The standard electrode potentials are E°(Zn²⁺/Zn) = -0.76 V and E°(Cu²⁺/Cu) = +0.34 V. (a) Calculate the cell EMF at 25 °C using the Nernst equation. (b) If the cell is connected to an external source that forces current in the opposite direction, which metal will be deposited at the cathode?
