A voltaic cell utilizes the following reaction: 4Fe 2+ (aq) + O 2 (g) + 4 H

Question:

A voltaic cell utilizes the following reaction:
4Fe2+(aq) + O2(g) + 4 H+(aq) → 4Fe3+(aq) + 2H2O(l)
(a) What is the emf of this cell under standard conditions?
(b) What is the emf of this cell when [Fe2+] = 1.3 M, [Fe3+]= 0.010 M, PO2 = 0.50 atm, and the pH of the solution in the cathode half-cell is 3.50?
