Gce Model Questions Vol1 2018 Chemistry Question 35
Practice objective / multiple choice question 35 from the 2018 Gce Model Questions Vol1 Chemistry examination.
A galvanic cell consists of a zinc electrode in \(0.010\) M \(\text{Zn}^{2+}\) solution and a copper electrode in \(0.10\) M \(\text{Cu}^{2+}\) solution at \(25^{\circ}\)C. Standard electrode potentials are \(E^{\circ}(\text{Cu}^{2+}/\text{Cu}) = +0.337\) V and \(E^{\circ}(\text{Zn}^{2+}/\text{Zn}) = -0.763\) V. (a) Calculate the cell EMF under these conditions. (b) If the cell delivers a constant current of \(0.500\) A for \(2.00\) h, how much copper (in grams) is deposited on the cathode?
