Chapter 5, Problem 5.22NP

Interpretation Introduction

Interpretation:

The entropy change (ΔS) and the enthalpy change (ΔH) associated with the transformation of 1.75 moles of Hg (l) initially at 0 C to 75 C at 1 bar needs to be calculated

Concept Introduction:

The enthalpy change for a system under conditions of constant pressure is given as:

  $\text{ΔH = n}{\displaystyle \int {\text{C}}_{\text{p}}\text{dT}}\text{ ------(1)}$

The entropy change for a system under conditions of constant pressure is given as:

  $\text{ΔS = n}{\displaystyle \int \frac{{\text{C}}_{\text{p}}}{\text{T}}}\text{dT ------(2)}$
