ECH 152B Homework #3 Due: Friday January 29, 2010 1) ( 20 points ) Estimate the fugacity of isobutylene as a gas: a. At 280 o C and 20 bar b. At 280 o C and 100 bar 2) ( 30 points ) Assuming that Equation (11.68) is valid for the vapor phase and that the molar volume of saturated liquid is given by Equation (3.72), prepare plots of f vs. P and φ vs. P for Chloroform at 200 o C for the pressure range from 0 to 40 bar. At 200 o C the vapor pressure of chloroform is 22.27 bar. 3) ( 30 points ) Experimental data taken from 0 to 50 bar give the fugacity of a pure gas to be: ) exp( CP P f - = Where P is the pressure in bar and C is a constant that depends only on temperature. For the region of 0 o C to 100 o C, C is given by T C 30 065 . 0 + - = Where T is in Kelvin. a. Find an equation of state for this gas that is valid from 0

Unformatted text preview: o C to 100 o C. b. What is the molar volume (in m 3 /mole) at 80 o C and 30 bar? 4) ( 20 points ) The excess Gibbs energy of a particular ternary liquid mixture is represented by the empirical expression, with parameters A 12 , A 13 , and A 23 functions of T and P only: 3 2 23 3 1 13 2 1 12 x x A x x A x x A RT G E + + = a. What is the physical interpretation of A 12 , A 13 , and A 23 ? b. Determine the implied expressions for ln(γ 1 ), ln(γ 2 ), and ln(γ 3 ). c. For species 1, determine expressions for ln(γ 1 ) for the limiting cases: x 1 0, x 1 1, x 2 0, and x 3 0. What do these limiting cases represent?...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
