We are asked to identify what type of cell is this and if this reaction will be spontaneous.
Voltaic cell (Galvanic Cell)
Recall that the greater the E°cell of a redox reaction, the more likely the reaction will occur (more spontaneous reaction)
E°cell > 0 → spontaneous in the forward direction
E°cell < 0 → nonspontaneous in the forward direction
We go through the following steps to identify the cell:
Step 1. Gather reduction potentials
Step 2. Identify the oxidation and reduction half-reactions
Step 3. Calculate cell potential
Step 4. Identify the type of cell
You construct an electrochemical cell in which you want to oxidize Ag to Ag + and reduce Ni2+ to Ni. At standard conditions, what type of cell is this, and will this reaction be spontaneous?
A. Electrolytic, non-spontaneous.
B. Electrolytic, spontaneous.
C. Voltaic, non-spontaneous.
D. Voltaic, spontaneous.
