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 V b a V V b = − − + ( ) ( ) α where: a RT P c c = 0 42748 2 . ( ) and b RT P c c = 0 08664 . and α = + − 1 1 2 S T r d i S is given by the following function of the acentric factor, ω . S = + − 0 48508 155171 015613 2 . . . ω 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: ( ) 1 ln ln ln R V a V G RT Z RT Z RT V b b V b α = − − + + − + 3. Oil reservoirs below ground frequently are in contact with underground water and, in connection with an oil drilling operation, you are asked to compute the solubility of water in...
