What is Molar diffusion?
Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles. Diffusion explains the net flux of molecules from a region of higher concentration to one of lower concentration. Once the concentrations are equal the molecules continue to move, but since there is no concentration gradient the process of molecular diffusion has ceased and is instead governed by the process of self-diffusion, originating from the random motion of the molecules. The result of diffusion is a gradual mixing of material such that the distribution of molecules is uniform. Since the molecules are still in motion, but an equilibrium has been established, the end result of molecular diffusion is called a "dynamic equilibrium".
How to Calculate Molar Flux of Diffusing Component A through Non-Diffusing B based on Partial Pressure of A?
Molar Flux of Diffusing Component A through Non-Diffusing B based on Partial Pressure of A calculator uses Molar Flux of Diffusing Component A = ((Diffusion Coefficient (DAB)*Total Pressure of Gas)/([R]*Temperature of Gas*Film Thickness))*ln((Total Pressure of Gas-Partial Pressure of Component A in 2)/(Total Pressure of Gas-Partial Pressure of Component A in 1)) to calculate the Molar Flux of Diffusing Component A, Molar Flux of Diffusing Component A through Non-Diffusing B based on Partial Pressure of A is defined as the molar flux between gaseous components A and B when diffusion of diffusing component A takes place with non-diffusing component B. Molar Flux of Diffusing Component A is denoted by Na symbol.
