Input data

Component A

Calculate the diffusivity coefficient, based in the kinetic theory of gases (includes the atraction and repulsion forces between molecules).

Applicale to Non-polar gases and non-reactive molecules.

Given the temperature and pressure, calculates the diffusivity coefficient, in cm²/s, by the Hirschfelder's equation:

D_{ab} = \frac{1.858 \cdot 10^{-3} \cdot T^\frac{3}{2}\cdot{\left(\frac{1}{M_A}+\frac{1}{M_B}\right)}^{\frac{1}{2}}}{P\cdotΩ_D\cdotσ_{AB}^2}

By selecting the component, return the Lennard-Jones parameters ( $σ$ e $\frac{E}{k}$ ) and the molar mass.
