Question 1

Faradays constant

Answer 1

9.6485x10^4 C*mol

Question 2

For standard potentials, how do u find Ecell std based off the cathode and anode standard potentials?

Answer 2

Do NOT invert and base them all off the reduction potentials, Ecell=Ecathode-Eanode

Question 3

What does n representing in free energy = -nFEcell?

Answer 3

The unit number of electrons in the redox equation. The nF gives u the total charge as it’s been observed that a mole of electrons is equivalent to a Faradays amount of charge. Ecell is the potential differencei n the battery. Recall the laws of physics, -qdeltav is work, and since electricity is relatively isothermal, the work is the Gibbs energy.
