CHEMICAL ENGINEERING THERMODYNAMICS COURSE NO.: CHEG5301 STUDENT: ___________________ COURSE: Thermodynamics INSTRUCTOR: Prof. Anderson SUBJECT: Problem Set 09 DUE: Wednesday, Oct. 22, 2008 1. Use the Soave modification of the Redlich-Kwong equation of state to calculate the vapor pressure of benzene at its reported normal boiling point of 80.1 ° C. The Soave-Redlich- Kwong equation is: P RT Vb a VV b = + ()() α where: a RT P c c = 0 42748 2 . () and b RT P c c = 0 08664 . and =+ − 11 2 ST r di S is given by the following function of the acentric factor, ω . S 0 48508 155171 015613 2 .. . ω Data for benzene: T c = 562.1 K; P c = 48.9 bar; ω = 0.212. The residual Gibbs energy for the S-R-K equation of state is: 1l n l n l n R Va V GR T Z R TZR T b  =− − + +  +  2.
