In an apparatus used to study the absorption of SO₂ in water, the global mass transfer coefficient K_G' obtained was 0.3 kmol/m².h.atm. Assuming that 40% of the mass transfer resistance is in the gas phase, calculate the overall mass transfer coefficient for the liquid phase, K_L', The system temperature is 30C and the pressure is maintained at 1 atm. Under these conditions, consider m = 5x10^-2.
