Chapter 10, Problem 10.17P

Interpretation Introduction

Interpretation:

To Estimate the fugacity and $\frac{G^R}{RT}$ of SO₂

Concept Introduction :

For the given conditions, we first find Reduced Temperature, T_r and Reduced Pressure, P_r $T_r=\frac{T}{T_C}$

and

  $P_r=\frac{P}{P_C}$

Fugacity can be found by Lee Kesler correlation as given below,

  $\varphi =({\varphi }^0){({\varphi }^1)}^{\omega }$

where the values of ${\varphi }^0$ and ${\varphi }^1$ are found in thermodynamic tables

Residual Gibbs Energy, G^R is defined as

  $G^R=RT\ln (\varphi )$

Where,

R = Universal Gas constant

T = Temperature = 600 K

T_c = Critical Temperature

P_c = Critical Pressure

  $\varphi$ = Fugacity Coeffecient = $\frac{f}{P}$

P = Pressure = 300 bar

f = Fugacity
