Chapter 19.4, Problem 1PE

Interpretation Introduction

Interpretation:

The equilibrium constant for the following cell reaction has to be calculated.

Concept introduction:

Thermodynamics of redox reactions:

The change in free-energy represents the maximum amount of useful work that can be obtained in a reaction: $\Delta {\text{G}}^0\text{=}{\text{-nFE}}_{cell}^0$

Relation between ${\text{E}}_{cell}^0$ and equilibrium constant (K) of a redox reaction: ${\text{E}}_{cell}^0=\frac{RT}{nF}\ln K$

Relation between $\Delta {\text{G}}^0$ and K:$\Delta {\text{G}}^0\text{=}\text{-}RT\ln K$
