Acetic acid (CH3 COOH) diffuses across a 1-mm thick film of non-diffusing water. The concentration of acetic acid on opposite sides of water film are 9% by weight (density=1012 kg/m³) and 4% by weight (density=1003.2 kg/m³). Calculate the rate of diffusion of acetic acid at 17 °C. DATA: The diffusivity of acetic acid in water at 25 °C = 1.11 x 10.⁹ m²/s Viscosity of acetic acid solution at 25 °C = 1.1336 x 10-³ Pa. Viscosity of acetic acid solution at 17 °C = 1.2883 x 10-³ Pa.s

Question
Acetic acid (CH3COOH) diffuses across a 1-mm thick film of non-diffusing water. The concentration of acetic acid on opposite sides of water film are 9% by weight (density=1012 kg/m³) and 4% by weight (density=1003.2 kg/m³). Calculate the rate of diffusion of acetic acid at 17 °C. DATA: The diffusivity of acetic acid in water at 25 °C = 1.11 x 109 m²/s Viscosity of acetic acid solution at 25 °C = 1.1336 x 10-³ Pa. Viscosity of acetic acid solution at 17 °C = 1.2883 x 10-³ Pa.s
