2. The values ​​of partial pressures of the vapors of the components in the system “chloroform (1 component) – diethyl ether (2 component)” are known for different molar fractions of the second component in the liquid phase. N2(l) 0 0.2 0.4 0.6 0.8 1
р1*10-4, Pa 0.316 .267 0.253 0.220 0.149 0.000
р2*10-4, Pa 0 1.879 2.253 2.479 2.706 3.056
Required:
1) plot on graph paper a graph of the partial pressures of the components versus the mole fraction of the second component (Fig. 1)
2. Plot the dependence of the total vapor pressure above the solution on the composition (on the same Fig. 1)
2) determine whether there are deviations from Raoult's law (positive or negative);
4) Calculate the activity coefficients of each component of the solution for the following compositions N2(l)= 0.3; 0.5; 0.7.
