Chapter 6, Problem 6.14NP

Interpretation Introduction

Interpretation : The value of $\Delta A$ for the isothermal compression of $2.95\text{ mol}$ of an ideal gas at $325\text{ K}$ from an initial volume of $60.0\text{ L}$ to a final volume of $20.5\text{ L}$ should be calculated.

Concept Introduction :

The Helmholtz free energy can be calculated as follows:

  $dA=-S.dT-P.dV$

Here,

A − Helmholtz free energy

S − entropy

T − temperature

P − pressure

V − volume
