Question: molecule A is contained inside a spherical shell (B), Molecule A needs to diffuse through shell before delivered to environment, concentration CA, = 0.235 mol/m3

molecule A is contained inside a spherical shell (B), Molecule A needs to diffuse through shell before delivered to environment, concentration

CA, = 0.235 mol/m3 at the inner surface of the shell and is negligibe at the outer surface. The diffusivity of molecule A In shell (B) is DAB= 1.46 x 10-12 m2/s. What is the total molar rate of A being released from the capsule (NA) in gmol/s

as well as the flux of A at the outer surface in gmol/sm^2

r1 =0.03 mm and r2=0.05mm.
