Solution: A voltaic cell utilizes the following reaction and operates at 298 K: 3Ce4 + (aq) + Cr(s)  →  3Ce3 + (aq) + Cr3 + (aq).What is the emf of this cell when [Ce4 + ] = 2.6 M , [Ce3 + ] = 0.16

A voltaic cell utilizes the following reaction and operates at 298 K:
3Ce^{4 +} (aq) + Cr(s)  →  3Ce^{3 +} (aq) + Cr^{3 +} (aq).

What is the emf of this cell when [Ce^{4 +} ] = 2.6 M , [Ce^{3 +} ] = 0.16 M , and [Cr^{3 +} ] = 1.6×10⁻² M ?
