Calculate z and v for ethylene at 25oc (298.15k) and 12 bar by the following equations:
(a) the gas equation (ans: z=1; v= 2066 cm3/mol)
(b) the truncated virial equation with the following experimental values of virial coefficients:
b = -140cm3 mol-1 c = 7200 cm6 mol-2 (ans: z= 0.929; v= 1919 cm3/mol)
(c) the generalized compressibility factor correlation (ans. z= 0.932; v = 1924 cm3/mol)
(d) the truncated virial equation [eq. (3.38)], with a value of b from the generalized pitzer correlation [eq. (3.63)]. (ans. z= 0.932; v = 1924 cm3/mol)
(e) the redlich / kwong equation (ans. z= 0.928; v = 1916.5 cm3/mol)
(f) the soave / redlich/ kwong equation (ans. z= 0.928; v = 1918 cm3/mol)
(g) the peng / robinson equation (ans. z= 0.92; v = 1900.6 cm3/mol)
