Question

State True (T) or false (f) of the following NA is defined as mass flux (g m ) of A based on a stationery observer. for binary gas phase system DAB = DBA. Gas phase diffusion coefficient is related to temperature as DAB alfa r^2.5 Liquid phase diffusion coefficient increases with Increase in viscosity of liquid. Gas phase diffusion coefficient value is In the range of 10 m /s. The basic material balance equation looks as Rate of mass (Input - Output + Generation = Accumulation) The general flux equation converted to the following when concentration of A is very high NA = -DAB DeltaCA Flck's law of mass transfer is not applicable with in concentration boundary layer For diffusion with chemical reaction of the type 2A (g) rightarrow 3B (g) the individual fluxes arerelated to each other as NA = 3/2 NB. For Equimolar Counter Diffusion NA = NB.

Explanation / Answer

State True (T) or false (f) of the following NA is defined as mass flux (g m ) o
