Chapter 18, Problem 18.106QE

a)

Interpretation Introduction

Interpretation:

${\text{E}}_{\text{cell}}^{\text{0}},{\text{ΔG}}^{\text{0}}\text{and}{\text{K}}_{\text{eq}}$ for the given reaction has to be given.

  $\text{Li}(\text{s})+{\text{I}}_2(\text{s})\to 2\text{LiI}(\text{s})$

Concept Introduction:

In voltaic cell, the maximum cell potential is directly related to the free energy difference between the reactants and products in the cell.

  $\begin{array}{c}{\text{ΔG}}^{\text{0}}{\text{= -nFE}}^{\text{0}}\\ \text{n = Number of moles transferred per mole of reactant and products}\\ \text{F = Faradayconstant=96485C/mol}\\ {\text{ E}}^{\text{0}}\text{= Volts = Work(J)/Charge(C)}\end{array}$

b)

Interpretation Introduction

Interpretation:

Effect in the voltage of battery as the reaction proceeds has to be given.
