2- The vapor pressure of pure benzene (M=78.12 amu) and puretoluene (M=92.14 amu) at 298.15 K are 103.1 Torr and 28.4 Torr,respectively. A solution is prepared from a mixture of 100.0 geach, under 1.000 atm pressure and equilibrium is established. i-What would be the composition of the vapor assuming the solution tobe an ideal one? (5 pts) ii- What are the changes in the chemicalpotentials of the liquid and gaseous benzene and toluene uponformation of the solution? (10 pts) iii- Calculate the activity andthe activity coefficient of benzene in the solution, if theexperimentally found vapor pressure of benzene was 60.23 Torr. (10pts) iv- Without doing explicit calculations, predict the activitycoefficient of toluene in the solution. (5 pts)
