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.
Diffusion rate (r) is directly proportional to average molecular velocity. Where; r 1 and r 2 are diffusion rates of gas 1 and gas 2, V 1 and V 2 are average molecular velocities of gases and M 1 and M 2 are molecular masses of gases. Equation given above is called also Graham's Diffusion Law. Now, we will give diffusion ratio of two different gases at different temperatures.
