A voltaic cell utilizes the following reaction and operates at 298 K:

3 Ce4+(aq) + Cr(s)→3Ce3+(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?

What is the emf of the cell when [Ce4+] = 0.010 M, [Ce3+] = 2.0 M, and [Cr3+] = 1.5 M?
