Assuming toluene (1) and heptane (2) form an ideal solution, answer the following: (a) (10 points) A solution of the two components that contains 62% toluene is slowly heated at constant pressure. When the solution begins to boil the temperature reads 120C. What is the pressure? (b) (10 points) The bubble pressure at 120C of a mixture of the two components is 2 bar. What is the dew pressure of this mixture at 120C ? (c) (10 points) A mixture of toluene and heptane that contains 61% toluene is at 120C,2.45 bar. What is the fugacity of toluene in this mixture? Additional Data: At 120CP1sat=3.0 bar. P2sat=1.81 bar
