Chapter 2, Problem 2A.8P

Interpretation Introduction

Interpretation: The work done during complete decomposition of ${\text{CaCO}}_{\text{3}}\left(\text{s}\right)$ at $1.\text{0 atm}$ pressure has to be calculated.  Also, the work done when the heating was carried out in an open container has to be calculated.

Concept introduction: In thermodynamics, work is defined as the form of mechanical energy that is transferred from system to another.  Due to the organized motion of atoms, work refers to the energy transfer.  An expression for the work done in an isothermal reversible expansion is,

    $dw=-pdV$
