diffusion coefficient see diffusion coefficient. coefficient of digestibility the proportion of a food that is digested compared to what is absorbed, expressed as a percentage. dilution coefficient a number that expresses the effectiveness of a disinfectant for a given organism.
In dilute aqueous solutions the diffusion coefficients of most ions are similar and have values that at room temperature are in the range of 0.6 Ã 10â9 to 2 Ã 10â9 m2/s. For biological molecules the diffusion coefficients normally range from 10â11 to 10â10 m2/s.
