Unformatted text preview: Torr. Assume that the solution is ideal. Assume there is only a trace of liquid present and the mole fraction of ethyl chloride in the vapor is 0.80 and then answer these questions: a. What is the total pressure and the mole fraction of ethyl chloride in the liquid? b. If there are 5.00 mol of liquid and 3.00 mol of vapor present at the same pressure as in part (a), what is the overall composition of the system? 5. At 39.9C, a solution of ethanol ( x 1 = 0.9006, P 1 * = 130.4 Torr ) and isooctane ( P 2 * = 43.9 Torr ) forms a vapor phase with y 1 = 0.6667 at a total pressure of 185.9 Torr. a. Calculate the activity and activity coefficient of each component. b. Calculate the total pressure that the solution would have if it were ideal.
