Chapter 17, Problem 17.24QE

(a)

Interpretation Introduction

Interpretation:

The sign of work done ‘w’ has to be predicted for the reaction,

  ${\text{Fe}}_{\text{2}}{\text{S}}_{\text{3}}\left(\text{s}\right)\text{+}{\text{6HNO}}_{\text{3}}\left(\text{aq}\right)\to 2\text{Fe}{\left({\text{NO}}_{\text{3}}\right)}_{\text{3}}\left(\text{aq}\right)\text{+}{\text{3H}}_{\text{2}}\text{S}\left(\text{g}\right)$

(b)

Interpretation Introduction

Interpretation:

The sign of work done ‘w’ has to be predicted for the reaction,

  ${\text{C}}_{\text{3}}{\text{H}}_{\text{8}}\left(\text{g}\right)\text{+}{\text{5O}}_{\text{2}}\left(\text{g}\right)\to {\text{3CO}}_{\text{2}}\left(\text{g}\right)\text{+}{\text{4H}}_{\text{2}}\text{O}\left(\text{l}\right)$
