112. Solving a chemistry problem

The following table shows the results of determining the partial concentration of the colloidal dispersion of kaolin as a function of time during rapid coagulation with electrolyte:
t,s 0 105 180 255 335 420 510
v*10-9,cm-3 5.0 3.90 3.18 2.92 2.52 2.00 1.92

Determine the rate constant from these data and compare it with what is expected from the theory of rapid coagulation at 20 degrees and a solvent viscosity of 1.0 cps
