139. Solving a chemistry problem

3. Using the dependence of the number concentration of particles on the coagulation time, calculate the initial concentration of particles, the rate constant of rapid coagulation and the time of half coagulation. Calculate and plot the curves of the dependences of the total numerical concentration of particles, the concentration of primary (single) and double particles from time t:
