Igcse Model Questions Vol1 2023 Chemistry Question 21
Practice objective / multiple choice question 21 from the 2023 Igcse Model Questions Vol1 Chemistry examination.
A galvanic cell is constructed as follows: Fe(s) | Fe^{2+} (unknown) || Cu^{2+} (0.10 M) | Cu(s). The standard reduction potentials are E°(Cu^{2+}/Cu) = +0.34 V and E°(Fe^{2+}/Fe) = -0.44 V. At 25 °C the measured cell emf is 0.75 V. (a) Calculate the concentration of Fe^{2+} in the cell. (b) Using the standard cell potential, calculate the equilibrium constant K for the overall cell reaction at 25 °C.
