36. Solution to Chemistry Problem

9. 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 4.586 3.866 3.4 3.066 2.533 0
р2*10-4, Pa 0 3.733 5.04 5.666 6.133 6.826
It is necessary:
1) to plot a graph of the dependence of partial and total pressure above the system 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.
