Redo Example 23.1 with just one change. Let us suppose that C_B is very low, or C_B = 1.

Example 23.1

Air with gaseous A bubbles through a tank containing aqueous B. Reaction occurs as follows:

For this system

For a point in the absorber-reactor where

(a) Locate the resistance to reaction (what % is in the gas film, in the liquid film, in the main body of liquid)
(b) Locate the reaction zone
(c) Determine the behavior in the liquid film (whether pseudo first-order reaction, instantaneous, physical transport, etc.)
(d) Calculate the rate of reaction (mol/m³ · hr)
