Example. The diffusivity of the vapour of a volatile liquid in air can be conveniently
determined by Winkelmann's method in which liquid is contained in a narrow diameter
vertical tube, maintained at a constant temperature, and an air stream is passed over
the top of the tube sufficiently rapidly to ensure that the partial pressure of the vapour
there remains approximately zero. On the assumption that the vapour is transferred
from the surface of the liquid to the air stream by molecular diffusion, calculate the
diffusivity of carbon tetrachloride vapour in air at 321 K and atmospheric pressure from
the following experimental data:

The vapour pressure of carbon tetrachloride at 321 K is 37.6 kN/m² and the density of
the liquid is 1540 kg/m³. Take the kilogram molecular volume as 22.4 m³.

- ICG Heterogeneous Catalysis Performance P10-3 t-Butyl alcohol (TBA) is an important octane enhancer that is used to replace lead additives in gasoline [Ind. Eng. Chem. Res., 27, 2224 (1988)]. TBA was produced by the liquid-phase hydration (W) of isobutene (I) over an Amberlyst-15 catalyst. The system is normally a multiphase mixture of hydrocar- bon, water, and solid catalysts. However, the use of cosolvents or excess TBA can achieve reasonable miscibility. The reaction mechanism is believed to be Derive a rate law assuming: I S (P10-3.1) I+S W.S (P10-3.2) WSZ W S+I SE TBA S+S (P10-3.3) TBA SZ TBA + S (P10-3.4) (a) The surface reaction is rate-limiting.

Derive an expression for the resulting velocity profile v as a function of y (distance from the plate), H, K, n, g, p, and b. Sketch three representative velocity profiles (each having, for simplicity, the same maximum velocity, which in practice would mean different values of к), for n 1, and comment briefly on the important features.
