Answer to Question #299367 in Chemical Engineering for SAVARA RAVITEJA

Question

Hydrochloric acid (A) diffuses through a thin film of water (B)

4 mm thick at 283 K and 1 atm ressure. The concentration of HCl at point 1 on

one boundary of the film is 12 wt % with density of 1060.7 kg/m3

and on the

other boundary, at point 2, is 4 wt % of density1020.15 kg/m3

. The diffusivity

of HCl in water at 293 K and 1.5 atm is 2.5 x 10-9 m

2

/s. Calculate the flux of

HCl considering water to be stagnant.
