Neco Model Questions Vol1 2018 Chemistry Question 31
Practice objective / multiple choice question 31 from the 2018 Neco Model Questions Vol1 Chemistry examination.
A galvanic cell is constructed as follows: Zn(s) | Zn^{2+} (0.010 M) || Cu^{2+} (0.10 M) | Cu(s) at 25°C. The standard reduction potentials are E°(Zn^{2+}/Zn) = -0.76 V and E°(Cu^{2+}/Cu) = +0.34 V. (a) Calculate the cell EMF at these concentrations. (b) If the cell is connected to an external battery of 1.10 V that opposes the spontaneous direction, will the overall reaction be spontaneous? Provide the EMF (to two decimal places) and answer "yes" or "no".
