Calculate the diffusivity coefficient, which is considered a good estimate for non-polar gases.
<br>The Fuller equation is recommended when it is not possible to obtain the Lennard-Jones parameters.
<br>Given the temperature, pressure, molar mass, and associated volume of the components, the diffusivity coefficient, in cm²/s, is calculated using the Fuller equation:
<br>$$ D_{AB} = 1 \cdot 10^{-3} \cdot \frac{T^{1.75}}{P \cdot \left( \sum v_A^{\frac{1}{3}} + \sum v_B^{\frac{1}{3}} \right)^2} \cdot \left( \frac{1}{M_A} + \frac{1}{M_B} \right)^{\frac{1}{2}} $$
