Chapter 19, Problem 19.133QP

Interpretation Introduction

Interpretation:

The maximum work respect with $\text{6}\text{.61 g Cr}$ should be calculated by cell potential.

Concept introduction:

Maximum work of the cell:

In thermodynamics the cell potential is known as maximum work of the cell and it is equal to free energy change of the cell and it is given by,

${\text{W}}_{\text{max}}\text{=ΔG}\text{=}{\text{-nFE}}_{\text{cell}}$

Where,

$\begin{array}{l}{\text{W}}_{\text{max}}\text{is}\text{maximum}\text{work}\\ \text{ΔG}\text{is}\text{free}\text{energy}\text{change}\\ \text{n}\text{is}\text{number}\text{of}\text{electron}\text{transferred}\\ \text{F}\text{is}\text{faraday constant}\\ {\text{E}}_{\text{cell}}\text{is}\text{cell potential}\end{array}$
