82. Using the data shown as follows to calculate ΔG° for the reaction (1 F = 96,485 coulombs): Fe(s) + Cu2+(aq) → Fe2+(aq) + Cu(s). The reduction potentials for Fe2+ and Cu2+ are as follows:Fe2+ + 2e– → Fe ε° = –0.44 VCu2+ + 2e– → Cu ε° = 0.34 V (A) –1.9 × 104 J (B) –1.5 × 105 J (C) 0 J (D) 1.9 × 104 J (E) 1.5 × 105 J
