Calculate the rate of diffusion of trichloroacetic acid (Mwt = 163.5 g/gmole) across non- diffusing methanol (Mwt = 32 g/gmole) solution of 2 mm thick at 20°C when the concentrations of the acid on the two opposite sides of the methanol film are 6% and 2% by weight of acid. The densities of 6% and 2% acid solutions are 1012 kg/m³ and 1003 kg/m³ respectively. The diffusivity at infinite dilution of trichloroacetic acid in methanol at 20°C is 1.862×10º m²/s.
