Question

Calculate the rate of diffusion of acetic acid across a film of non diffusing water

Answer 1

Calculate the rate of diffusion of acetic acid [A] in [K mol / m2 - s] across a film of non - diffusing water (B) solution 1mm thick at 17oc when the concentrations on opposite sides of the film are respectively 9 wt% and 3 wt % acid ( The diffusivity of acetric acid in the solution is 0.95 ×× 10-9 m2/s )

{H20=18,CH3COOH=60 [Assume ρ=1000 kgm3]H20=18,CH3COOH=60 [Assume ρ=1000 kgm3]}

Answer

9.28 × 10-7
