74. 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 disperse 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.

Coagulation time t, sec. 0 335 510 600 800
Total number of particles of the dispersed phase, VS 10-14 particles/m3 5.00 2.52 1.92 1.75 1.49
