36. Solution to Chemistry Problem

Product description

• 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:

• 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
• to determine whether there are deviations from Raoult's law (positive or negative, significant or insignificant);
• Calculate the activity coefficients of each component of the solution with the following compositions N2(l) = 0.3; 0.5; 0.7.
