Problem Set 10 – CEM 383 Fall 2007 Due at the start of class on 11/26/07 1. A graduate student prepares a saturated solution of I 2 in benzene (C 6 H 6 ) at 298K by dumping an excess of solid I 2 into the solvent, putting the beaker containing the solution on a magnetic stirring plate and letting it mix for two hours while he works out at the gym. When the student returns, the solution has reached equilibrium and there is a small pile of solid I 2 in the bottom of the beaker. a) Write down expressions for the chemical potentials of I 2 (solid) and I 2 (C 6 H 6 ) (I 2 dissolved in benzene). b) Calculate the activity of I 2 in solution for this system at 298K, given that Δ f G o ( I 2 ( C 6 H 6 ; X )) = 7.1 kJ / mol and that Δ f G o ( I 2 ( solid )) = 0 . The X in the above notation, I 2 (C6H6:X)) indicates that the standard state is on the mole fraction scale. c) Calculate the equilibrium constant for the dissolving of I 2 at 298 I 2 ( s ) I 2 ( C 6 H 6 ) 2. Use the following data for three different aqueous solutions of CaCl
