Chapter 17, Problem 17.23QE

(a)

Interpretation Introduction

Interpretation:

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

  ${\text{2NaHCO}}_{\text{3}}\left(\text{s}\right)\text{+}{\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}\left(\text{aq}\right)\to {\text{Na}}_{\text{2}}{\text{SO}}_{\text{4}}\left(\text{aq}\right)\text{+}{\text{H}}_{\text{2}}\text{O}\left(\text{l}\right)\text{+}{\text{2CO}}_{\text{2}}\left(g\right)$

(b)

Interpretation Introduction

Interpretation:

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

  $\text{HCl}\left(\text{g}\right)\text{+}{\text{NH}}_{\text{3}}\left(\text{g}\right)\to {\text{NH}}_{\text{4}}\text{Cl}\left(\text{s}\right)$
