Chapter 17, Problem 40E

(a)

Interpretation Introduction

Interpretation:

Two galvanic cells with two different chemical reactions are given. The value of $E°$ for both the cells is to be calculated.

Concept introduction

The galvanic cell converts chemical energy into electrical energy while the electrolytic cell converts electrical energy into chemical energy.

The species at anode undergoes oxidation while the species at cathode undergoes reduction and the electrons generated at the anode are transferred through wire to the cathode.
