The computer program ZB2 was used to study simulated coagulation rate for the system containing spherical sol particles and spherical coagulant particles. The system performance was verified to the particle-cluster model of a fast and perikinetic coagulation process that fulfils Smoluchowski and/or Muller equations. The rate of the coagulation process satisfied both the kinetic equation of a first-order reaction and a second-order reaction. However, chosen concepts and models in the theory of bidispersive sol coagulation have been negatively verified. Also, attempts have been made to modify the Muller integral equation for selected boundary conditions.
