"WebThis suggests two important limiting cases for reactions in solution. For water at room temperature, k1 is typically 10 9 -10 10 dm –3 mol –1 s –1 and k2 is around 10 –9 -10 –10 dm –3 mol –1 s –1. Given these values, k3 > 10 12 s –1 implies diffusion control, while values < 10 9 s –1 are indicative of activation control. " - Diffusion thermodynamics
