1. The following table shows the specific surface area Ssp, the concentration of the dispersed phase s, and the half-coagulation time Q for a number of lyophobic dispersed systems. Calculate and plot the curve of the change in the numerical concentration of particles (the total number of particles per unit volume) during coagulation for the following time intervals: Q/5, 0/4, Q/3, Q/2, Q, 3Q/2, 3Q s
Particle composition Ssp, 107 m-1, s, g/m3 Density g/cm3 Q s
