36. Solution to Chemistry Problem

7. The values ​​of partial pressures of the vapors of the components in the system "chloroform (1 component) - diethyl ether (2 component)" are known at different mole 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 1.933 1.48 0.92 0.46 0.165 0
р2*10-4, Pa 0 0.46 1.287 2.666 4.093 5.333
It is necessary:
1) to plot on graph paper a graph of the dependence of the partial pressures of the components on the mole fraction of the second component
2) to determine whether there are deviations from Raoult´s law (positive or negative, significant or insignificant);
4) Calculate the activity coefficients of each component of the solution with the following compositions N2(l) = 0.3; 0.5; 0.7.
