21. Solving a chemistry problem

14. When coagulating a sol with an electrolyte, data on changes in the partial concentration n were obtained, given in Table 6.6. Calculate the constants k and Q of the Smoluchowski kinetic equation and the distribution curves of 1st, 2nd and 3rd order particles. Calculate the theoretical value of the coagulation rate constant and check the applicability of Smoluchowski´s theory to the coagulation of the studied sols. Coagulation was studied at a temperature of 298 K. The viscosity of the dispersion medium is 1*10-3 Pa*s.
