Chapter 6, Problem 6.16NP

Interpretation Introduction

Interpretation : The change in the Helmholtz energy should be calculated. The reversible work performed $W_{rev},\Delta \text{S and }\Delta \text{U}$ should be calculated.

Concept Introduction :

The relation between change in internal energy, Helmholtz energy and entropy is represented as follows:

  $\Delta U=\Delta A+T.\Delta S$

Here, T is temperature.

Also, the value of change in Helmholtz energy is equal to the reversible work done.
