Homework Equations
Nernst Equation where Q = [product]/[reactants], R = 8.314, F = 96500
The Attempt at a Solution
I got E° to be 0.012 V because E° of cathode - E° of anode. -0.131 - (-0.143) = 0.012.
The balanced equation I got was: Pb2+ + Sn → Pb + Sn2+
For the values of Q, I added 0.349 M to the concentration of Sn2+ as it's the product, and I subtracted 0.349 M from the concentration of Pb2+ as it's the reactant.
Plugging everything into the equation:
E = 0.012 V - ((8.314 * 271)/(2 * 96500)) * ln(1.318/0.576) = 0.0023 V. This answer is wrong, but I cannot figure out what I'm doing wrong here. Please help!
