Problem # 1: (6.1.1 of the 4th edition)
18.1-1. Diffusion of Methane Through Helium. A gas of CH 4 and He is
contained in a tube at 101.32 kPa pressure and 298 K. At one point,
the partial pressure of methane is = 60.79 kPa, and at a point
PA1
0.02 m distance away, PA2 = 20.26 kPa. If the total pressure is
constant throughout the tube, calculate the flux of CH4 (methane) at
steady state for equimolar counterdiffusion.
Az
Ans. J₂ = 5.52 × 10−5 kg mol A/s · m²(5.52 × 10−6 g mol A/s · cm²)
Hint: See example 18.1-1
Problem # 2 (6.3-1 of the 4th edition)
9.2-1. Diffusion of A Through Stagnant B in a Liquid. The solute HCl
(A) is diffusing through a thin film of water (B) 2.0 mm thick at 283
K. The concentration of HCl at point 1 at one boundary of the film is
12.0 wt % HCl (density p₁ = 1060.7 kg/m³), and at the other
boundary at point 2 it is 6.0 wt % HCl (p2 = 1030.3 kg/m³). The
diffusion coefficient of HCl in water is 2.5 × 10-9m²/s. Assuming
steady state and one boundary impermeable to water, calculate the
flux of HCl in kg mol/s · m².
