46. Solving a chemistry problem

9. Using the experimental data, calculate the average value of the Smoluchowski fast coagulation rate constant k for a sulfur sol coagulated with an ammonium chloride solution:
Coagulation time t, s 0 1 2 4 10
Total number of particles in 1 m3 n•10-17 16.00 1.78 0.99 0.50 0.20
Compare the obtained value with the value of the constant calculated theoretically. Viscosity η=1•10-3 N•s/m2. Make a conclusion about the applicability of Smoluchowski´s theory to sol coagulation
