If x and y are the molar fractions of a certain component (A) in the liquid and gas phases, respectively, and xa and xb represent the molar fractions of component A in the liquid phase at the inlet and outlet, respectively, and xa* and xb* represent the molar fractions of component A in the gas phase at the inlet and outlet, respectively, when reaching equilibrium with the liquid phase, answer the following questions:

(b) Continuing from the previous question, if the air flow rate (V) is 1.5 times the ammonia flow rate (L), the entire apparatus has eight plates, and the overall plate efficiency is 75%, calculate the ammonia removal rate under this condition using the Kremser equation. (12%)

(c) Continuing from the previous question, if the air flow rate (V) is increased while keeping other conditions constant, how will the ammonia removal rate change? Please explain why.
