At high pressure CO₂ is absorbed into a solution of NaOH in a packed column. The reaction is as follows:

Find the rate of absorption, the controlling resistance, and what is happening in the liquid film, at a point in the column where p_A = 10⁵ Pa and C_B = 500 mol/m³.

This problem was adapted from Danckwerts (1970).
