Determine B and C for this gas at this temperature, ... 1 2 + + + = v C v B RT Pv b. Estimate the change in Helmholtz energy in compressing this gas from a molar volume of 10000 cc to 100 cc. 5. Calculate the molar volume of a binary mixture containing 30 mol % nigrogen(1) and 70 mol % n-butane(2) at 188 o C and 6.9 MPa by the following methods: a. Assume the mixture to be an ideal gas b. Assume the mixture to be an ideal solution with the volumes of the pure gases given by 1 BP Z RT = + and the virial coefficients given below. c. Use the second virial coefficients predicted by the generalized correlation for B. d. Use the following values for the second virial coefficients. Data: B 11 =14 B 22 = -265 B 12 = -9.5 (Units are cm 3 /gmole) e. Using the Peng-Robinson equation. f. How good is the ideal solution approximation?...
