Chapter 17, Problem 51E

(a)

Interpretation Introduction

Interpretation:

The set up of two galvanic cells is given. The value of maximum work that can be obtained from the given galvanic cell is to be calculated.

Concept introduction:

The species with higher reduction potential undergoes reduction at the cathode while the species with lower reduction potential undergoes oxidation at the anode. The change in Gibbs free energy is the useful amount work that can be done and negative value of $\Delta G°$ shows that the reaction is spontaneous in nature.

To determine: The value of maximum work that can be obtained from the given galvanic cell.
