35. Solving a chemistry problem

73. 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.
Instruction. It is expedient to represent the Smoluchowski equation in the form:
VO /VS = f(t), after which the half-coagulation time is determined graphically.
