Chem 3433 – Problem Set 7 Due before class on 10/19/11 1. Find G mix , S mix and H mix for an ideal solution prepared from 1.28 mol of benzene and 1.09 mol of toluene at 20ºC. 2a. Derive Equation 5.41 using Raoult’s Law. 2b. Next, derive Equation 5.45. 3a. Reproduce Figures 5.30 and 5.31 using a spreadsheet 3b. Make a plot like Figure 5.32, assuming that * * b a P P = 10. 4a. The vapor pressure is measured over a mixture of acetone and chloroform. X acetone 0.0 0.2 0.4 0.6 0.8 1.0 P acetone /torr 0 35 82 142 219 293 P chloroform/ torr 347 270 185 102 37 0 Plot the total pressure, the pressure of acetone, and pressure of chloroform versus the mol fraction of acetone in the solution. Is the solution ideal of non-ideal? From the graph, use the first two points to estimate the Henry’s Law constant for acetone and chloroform. 4b. Calculate the case 1 activities for acetone and chloroform 4c. Calculate the case activities for acetone and chloroform 5. Three mol of A are mixed with thee mol of B at P
