Diffusion Coefficient Formula
The following two example problems outline the steps and information needed to calculate the Diffusion Coefficient.
D = (1/f) * k * t
Variables:
- D is the Diffusion Coefficient ( )
- f is the frictional coefficient
- t is the absolute temperature
- k is the Boltzmann Constant = 1.380649 * 10^-23 (m^2-kg/(s^2-K))
To calculate the diffusion coefficient, divide 1 by the friction coefficient, then multiply by the absolute temperature and the Boltzmann constant.
How to Calculate Diffusion Coefficient?
The following steps outline how to calculate the Diffusion Coefficient.
- First, determine the frictional coefficient.
- Next, determine the absolute temperature.
- Next, gather the formula from above = D = (1/f) * k * t.
- Finally, calculate the Diffusion Coefficient.
- After inserting the variables and calculating the result, check your answer with the calculator above.
