142. Solving a chemistry problem

8.16. Using experimental data, verify the theory of rapid coagulation of an aqueous suspension of kaolin with an initial concentration of v0 = 5 * 10 ^ 14 ppm / m3 at a temperature of 289 K, dispersion viscosity
Wednesday n = 1 * 10–3 Pa * s. Determine the half coagulation time and coagulation constant.
