Chapter 14, Problem 14.8P

(a)

Interpretation Introduction

Interpretation:

Diagram of cell has to be drawn.

Concept Introduction:

Redox reaction is reaction that includes change in oxidation number of molecule, atom or ion and this changes are due to transfer of electron from one species to another. A complete reaction involves oxidation and reduction. Cell potential is evaluated by expression as follows:

  $E_{\text{cell}}^{°}=E_{\text{oxidation}}^{°}+E_{\text{reduction}}^{°}$

(b)

Interpretation Introduction

Interpretation:

Half-reaction for the each half cell has to be written.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

Direction of electron flow, identification of cathode and anode and overall cell reaction has to be written.

Concept Introduction:

Refer to part (a).
