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?...
