35. Solving a chemistry problem

71. Calculate the half-coagulation time and the coagulation rate constant using the experimental data obtained using an ultramicroscope on the change in the total number of particles during the coagulation of a lyophobic dispersed system under the influence of an electrolyte.
Note: It is expedient to represent the Smoluchowski equation in the form:
VO /VS = f(t) after which the half-coagulation time is determined graphically.

71.
Coagulation time t, sec. 0 7.0 15.0 20.2 28.0
Total number of particles of the dispersed phase, VS 10-14 particles/m3 32.2 24.2 19.9 16.7 14.2
