19. Based on experimental data on the dependence of surface tension ( b ) on the composition of the binary solution A - B, build the dependence of the adsorption of component B according to Guggenheim on the composition of the solution:
xB 0 0.05 0.1 0.2 0.3 0.4 0.5
b, mJ/m2 125 90 82 69 61 55 53
The solution is considered ideal.
