7. A galvanic cell is constructed based on the following standard reduction potentials at 25 °C:
La3+ +3e-→La E° = -2.37 V
Fe2+ +2eFe E° = -0.44 V
Which of the following statements is correct? (Faraday constant is 96500 C/mol.)
(A) The cell potential with all components in their standard state is 3.42 V.
(B) The cathode compartment would be composed of La3+/La.
(C) Three electrons are transferred per unit of cell reaction.
(D) When [Fe2+] = 2.00 x 10-4M and [La³+] = 2.00 x 10-3 M, the cell potential is >1.93 V.
(E) The △G° for this cell is -1117.5 kJ.
