Chapter 17, Problem 17.50SP

Interpretation Introduction

Interpretation:

The change in free-energy has to be calculated.

Concept Introduction:

Change in free-energy:

The change in free-energy, $\text{ΔG}$ is a thermochemical quantity.  The values of $\text{ΔG}$ and $\text{E}$ are directly proportional to each other and are connected by the equation,

$\text{ΔG}\text{=}\text{-nFE}$

Where, $\begin{array}{l}\text{n}\text{=}\text{number}\text{of}\text{moles}\text{of}\text{electrons}\text{transferred}\\ \text{F}\text{=}\text{Faraday}\text{constant}\text{(96,500}\text{C/mol}{\text{e}}^{\text{-}}\text{)}\end{array}$
