Calculate the rate of diffusion of n-Butanol (A) across a film of non-diffusing water (B) solution of 1 mm thick at 25°C. The concentrations of n-Butanol on the opposite sides of the film are known to be 12 wt% and 4 wt% respectively. Data: the diffusivity of (A) in the solution is 0.95×10-9 m²/sec at 25°C, the density of (A) is 810 kg/m', the density of (B) is 1000 kg/m³ , MwtButanol) = 74.12 g/gmol, Mwt(Water) = 18 g/gmol.

Question
Q2) Calculate the rate of diffusion of n-Butanol (A) across a film of non-diffusing water (B) solution of 1 mm thick at 25°C. The concentrations of n-Butanol on the opposite sides of the film are known to be 12 wt% and 4 wt% respectively. Data: the diffusivity of (A) in the solution is 0.95×10-º m²/sec at 25°C, the density of (A) is 810 kg/m', the density of (B) is 1000 kg/m³ , MwtButanol) = 74.12 g/gmol, Mwt(water) = 18 g/gmol.
