###### FREE Expert Solution

We are asked to calculate for the Ecell for the reaction

Cu(s) | Cu2+(0.017 M) || Ag(s), (Ag+ = 0.18M)

Recall that the Nernst Equation relates the concentrations of compounds and cell potential.

Ecell = cell potential under non-standard conditions
cell = standard cell potential
n = mole e- transferred
Q = reaction quotient = products/reactants

We're going to calculate for the Ecell using the following steps:

Step 1: Identify the anode and the cathode in the reaction and write the overall reaction
Step 2:
Calculate Ecell using the Nernst Equation.
