5. Find graphically the time of half coagulation for selenium hydrosol at 300 K according to the data:
time, s 0.15 20 30 60
concentration*10-14, particles/m3 32 19.5 17.2 14 8.95
Compare the obtained value with the theoretically calculated one. The viscosity of the medium is 1 cp at 293 K. Is the Smoluchowski equation applicable to describe the coagulation kinetics of a given sol?
