Question 11 IGCSE_MODEL_QUESTIONS_VOL1 • 2019 • CHEMISTRY • objective

A galvanic cell is set up with a fluorine electrode (F₂ gas at 1 atm) in a 0.10 M KF solution as the cathode, and a chlorine electrode (Cl₂ gas at 1 atm) in a 0.10 M KCl solution as the anode. Standard reduction potentials are \( \mathrm{F_2 + 2e^- -> 2F^-} \) E° = +2.87 V and \( \mathrm{Cl_2 + 2e^- -> 2Cl^-} \) E° = +1.36 V. (a) Write the overall cell reaction. (b) Calculate the standard cell potential \(E^\circ_{\text{cell}}\). (c) Determine the standard Gibbs free energy change \( \Delta G^\circ \) for the cell reaction.

Answer Options

A. E°cell = 1.51 V; ΔG° = -1.45×10⁵ J
B. E°cell = 1.51 V; ΔG° = -2.91×10⁶ J
C. E°cell = 0.51 V; ΔG° = -2.91×10⁵ J
Correct Answer D. E°cell = 1.51 V; ΔG° = -2.91×10⁵ J
Correct Answer
D
Correct Option:
E°cell = 1.51 V; ΔG° = -2.91×10⁵ J
