Chapter 4, Problem 4B.14E

Interpretation Introduction

Interpretation:

The work done for the each given pathways has to be identified.

Concept Introduction:

The system can done two kind of works.  The one is the work of expansion which is the work which arises from the change in the volume of the system.  On the other hand the second work done is the work of non-expansion which does not involve any change in the volume of the system.  The expression for calculating the work of reversible expansion is shown below.

    $w=-P_{\text{ex}}\Delta V$

The expression for calculating the work of isothermal expansion is shown below.

  $w=-nRT\ln \left(\frac{V_f}{V_i}\right)$
