Neco Model Questions Vol1 2019 Chemistry Question 34
Practice objective / multiple choice question 34 from the 2019 Neco Model Questions Vol1 Chemistry examination.
A galvanic cell is constructed as follows: Zn|Zn\(^{2+}\) (0.010 M) || Cu\(^{2+}\) (0.10 M)|Cu. Standard reduction potentials are \(E^\circ_{Cu^{2+}/Cu}=+0.34\) V and \(E^\circ_{Zn^{2+}/Zn}=-0.76\) V. (a) Calculate the cell potential at 25 °C using the Nernst equation. (b) If the cell is allowed to run until the Zn\(^{2+}\) concentration rises to 0.10 M (Cu\(^{2+}\) remains at 0.10 M), what is the new cell potential? Assume temperature stays at 25 °C.
