Consider absorption of CO2 (A) by a concentrated aqueous solution of NaOH (B) in a beaker as shown in the figure (Set z = 0 at the bottom of the beaker and z = L at the gas-liquid interface). Here gas A dissolves in liquid B and diffuses isothermally into the liquid phase. As it diffuses, A also undergoes an irreversible first-order homogeneous reaction: A + B AB. The reaction rate is rA = - k1cA. Find the concentration profile of A in liquid B and the molar flux at the interface.
