The Unidirectional Diffusion of a Gas A though a second stagnant Gas B (N_b = 0) is represented by N_A which is the diffusive flux of component i through area A in z direction.
Diffusive equilibrium is when the concentrations of all materials are equally distributed. This equation uses a value for the Universal Gas Constant, R, with units of (liter*atm / mol*K).  Molecular Diffusion is quantified as diffusive flux measured in units of mole/(time x area).  This equation utilizes different partial pressure samples. lm represents the 'log mean' of the samples taken.
