A voltaic cell utilizes the following reaction and operates at 298 K:
3 Ce4+(aq) + Cr(s) → 3 Ce3+(aq) + Cr3+(aq)
(a) What is the emf of this cell under standard conditions?
(b) What is the emf of this cell when [Ce4+] = 3.0 M, [Ce3+] = 0.10 M, and [Cr3+] = 0.010 M?
(c) What is the emf of the cell when [Ce4+] = 0.010 M, [Ce3+] = 2.0 M, and [Cr3+] = 1.5 M?
