An extended particle growth rate equation was proposed. This equation is based on the most simplified solution of the collision and coalescence model and can be used both in the free molecular region and in the continuous region under changing conditions. In the free molecular region, transition region, and continuous region, the dependence orders of mean particle size on the product of initial concentration of monomer and growth time were found to be 2/5, 1/4, and 1/3 respectively.
