We’re being asked to determine the cell notation for the redox reaction shown below:

Mn2+ (aq) + 2 e- ⇌ Mn(s)                   E° = -1.18 V

Cr3+ (aq) + 3 e-⇌ Cr(s)                      E° = -0.41 V

When writing a cell notation, we use the following format – “as easy as ABC To determine the cell notation of the reaction, we will use the following steps:
Step 1: Determine the anode and the cathode.
Step 2Write the cell notation of the reaction.
