A packed tower has been designed to strip component A from an aqueous stream into a counter-flowing air stream. At a given plane in the tower, the concentrations of the two adjacent streams are p_A, _G = 4 × 10³ Pa and c_A, _L = 4 kg mol/m³ of solution. Under the given flow conditions, the overall gas mass-transfer coefficient, K_G is equal to 2:46 × 10^-8 kg mol/m² s Pa and 60% of the resistance to mass transfer is encountered in the gas phase. At the tower's operating condition of 290 K and 1:013 × 10⁵ Pa, the system satisfies Henry's law with a Henry's law constant of 1400 Pa/(kg mol/m³).

Determine

a. the individual gas-film coefficient, k_G;

b. the individual liquid-film coefficient, k_L;

c. the interfacial gas concentration, p_AL;

d. the overall liquid mass-transfer coefficient, K_L.
