Chapter 17, Problem 17.26QE

(a)

Interpretation Introduction

Interpretation:

The value of work done has to be calculated for the reaction,

  $\text{2K}\left(\text{s}\right)\text{+}{\text{2H}}_{\text{2}}\text{O}\left(\text{l}\right)\to \text{2KOH}\left(\text{s}\right)\text{+}{\text{H}}_{\text{2}}\left(\text{g}\right)$

(b)

Interpretation Introduction

Interpretation:

The value of work done has to be calculated for the reaction,

  ${\text{2Fe}}_{\text{2}}{\text{O}}_{\text{3}}\left(\text{s}\right)\text{+}\text{3C}\left(\text{s}\right)\to \text{4Fe}\left(\text{s}\right)\text{+}{\text{3CO}}_{\text{2}}\left(\text{g}\right)$
