The vapor pressure of CC14 is 33.85 torr at T= 298K. The Henry's lawconstant for the solution is 122.36 torr. The non-standard unit for the Henry's law constant isdue to the concentration of Br2 being expressed as mole fraction. Calculate the following for aXBr2 = .07solution:a. Vapor pressure of CCl4.|b. Vapor pressure of Br2.c. Total pressure.d. Composition of the vapor phase.

Given data: Vapor pressure of CCl4 = 33.85 torr Temperature = 298 K Henry’s constant for the solution = 122.36 torr Composition of Br2 in the solution = 0.07A solution of Br2 in CCl4 is given. It is also given that the solution will behave as an ideal solution. (a) The vapor pressure of CCl4 is calculated as follows: The composition of Br2 in the solution (xBr2) = 0.07 Therefore the composition of CCl4 (xCCl4) in the solution becomes, xCCl4 = 1 - xBr2=1-0.07=0.93 The formula to calculate the vapor pressure is, pCCl4v = xCCl4pCCl4 ........... (1) Where, pCCl4 represents the vapor pressure of pure CCl4. xCCl4 represents the composition of CCl4 in the liquid phase.xCCl4 = 0.93 pCCl4 = 33.85 torr Plugin the values in equation (1) pCCl4v= 0.93 ×33.85 torr= 31.48 torr(b) Since the solution is ideal and dilute, the Henry’s law is applicable. According to the Henry’s law, the partial pressure of the gas is directly proportional to the concentration of gas in the liquid phase. The vapor pressure of Br2 is calculated as follows: pBr2v = KH × xBr2 ............ (2) Where, pBr2v represents the vapor pressure of Br2. KH represents the Henry’s constant. xBr2 represents the composition of Br2 in the liquid phase. xBr2 = 0.07 KH = 122.36 torr Plugin the values in equation (2) pBr2v = 122.36 torr × 0.07=8.56 torr(c) The total pressure of the solution is calculated as follows: P = pCCl4v + pBr2v .............. (3) Where, P represents the total pressure. pCCl4v represents the vapor pressure of CCl4. pBr2v represents the vapor pressure of Br2. pCCl4v = 31.48 torr pBr2v = 8.56 torr Plugin the values in equation (3) P = 31.48 torr +8.56 torr=40.04 torr(d) Composition of vapor phase is calculated as follows: yi = pivP ........... (4) Where, yi represents the composition of ith species in vapor phase. P represents the total pressure. piv represents the vapor pressure of ith species. P = 40.04 torr pCCl4v = 31.48 torr Plugin the values in equation (4) yCCl4 = 31.48 torr40.04 torr=0.786 Similar the composition of Br2 in the vapor phase is calculated. P = 40.04 torr pBr2v = 8.56 torr Plugin the values in equation (4) yBr2 = 8.56 torr40.04 torr=0.214
