(a)

Interpretation Introduction

Interpretation:

The chemical equation for the reaction of the given cell has to be written.

The given cell reaction is $\text{Pt}\left(\text{s}\right)\left|{\text{H}}_{\text{2}}\left(\text{g}\right)\right|{\text{H}}^{\text{+}}\left(\text{aq}\right){\text{||Co}}^{\text{3+}}\left(\text{aq}\right){\text{,Co}}^{\text{2+}}\left(\text{aq}\right)|\text{Pt}\left(\text{s}\right)\text{.}$

(b)

Interpretation Introduction

Interpretation:

The spontaneity of the cell reaction has to be predicted if the cell potential is positive.
