Chapter 18, Problem 93E

Interpretation Introduction

Interpretation:

The sign of ${\text{ΔG}}_{\text{rxn}}^{\text{ο}}$ and ${\text{E}}_{\text{cell}}^{\text{ο}}$ for the given reaction is to be predicted.

Concept introduction:The relationship between standard change in free energy for an electrochemical cell, number of moles of electrons transferred, Faraday’s constant and standard cell potential is,
   ${\text{ΔG}}^{\text{ο}}=-{\text{nFE}}_{{}_{\text{cell}}}^{\text{ο}}$

To determine:The sign of ${\text{ΔG}}_{\text{rxn}}^{\text{ο}}$ and ${\text{E}}_{\text{cell}}^{\text{ο}}$ for the given reaction.
