Chapter 21, Problem 21.35P

Interpretation Introduction

Interpretation:

The way how the standard reference electrode used to determine the $E^{\circ }{}_{cell}$ values has to be identified.

Concept Introduction:

The Standard Gibb’s free energy change and the standard cell potential are related as followed:

$\text{Δ}°\text{G}\text{=}\text{-nFE}{°}_{\text{cell}}$

n - Number of electrons involved per equivalent of the net redox reaction in the cell

F - Faraday’s Constant (96500 C)

$\text{E}{°}_{\text{cell}}$ - Standard cell potential.
