Chapter 4, Problem 4A.2BST

Interpretation Introduction

Interpretation:

The process in which more work is done at $\text{30}°\text{C}$ 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 that 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 expansion is shown below.

    $w=-P_{\text{ex}}\Delta V$

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

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