Mass Transfer The diffusivity (D) in a binary gas mixture is related to the pressure (P) as D ∝ 1/P0.5 D ∝ P0.5 D ∝ 1/P1.5 D ∝ 1/P D ∝ 1/P0.5 D ∝ P0.5 D ∝ 1/P1.5 D ∝ 1/P ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Though, theoretically the adsorption & desorption isotherms is expected to coincide but sometimes at least a part of the isotherms does not coincide and this phenomenon is known as adsorption hysterisis. In such cases, the desorption equilibrium pressure is __________ that obtained for adsorption.
