Chapter 17, Problem 48E

(a)

Interpretation Introduction

Interpretation:

The reactions taking place in two different galvanic cells are given. The $E°$ of the given galvanic cells, the spontaneity of the reactions and balanced chemical equation for each cell is to be stated.

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.

To determine: The set up of the cell given in the chemical equation and the direction of electron flow, identification of the cathode and anode and balanced chemical equation.
