Chapter 11, Problem 120CP

Interpretation Introduction

Interpretation:Concentration of ${\text{M}}^{a+}$ is to be calculated. Also, value of $w_{\text{max}}$ for electrochemical cell is to be determined.

Concept introduction:Study of interchange between electrical and chemical energy falls under branch of chemistry called electrochemistry. It includes occurrence of oxidation and reduction reactions. This includes production of electric current from chemical reaction and vice-versa.

Expression for maximum work is as follows:

  $w_{\text{max}}=-q{E}_{\text{max}}$

Where,

• $w_{\text{max}}$ ismaximum possible work.
• $q$ is amount of charge.
• $E_{\text{max}}$ ismaximum potential of cell.
