It is proposed to absorb a pure gas in a fresh solvent. Based on the experimental results, it was found that the transfer mechanism follows penetration theory. Initially, the transport rate is limited by the rate at which the gas molecules can reach the surface. The maximum possible rate of transfer of gas at ambient conditions (20° C and 1 atm.) is 50 m³/m².s. (i) (11) If the gas solubility is 0.04 kmol/m³, estimate the equivalent resistance. If the diffusivity in the liquid phase is 1.8 x 109 m²/s, at what time after the initial exposure will the resistance attributable to access of gas be equal to 10% of the total resistance of the transfer?
