Estimate the overall liquid-side mass transfer coefficient at 25celsuis for o2 from h2o intonair. For oxygen in air the diffusion coefficient is 0.23cm/s. For oxygen in water the diffusion coefficient is 2.1×10^-3cm/s. Henry's constant is 769L. atm/mol. Use the two film theory and assume the film thickness is 0.01cm for both gas and liquid phase. Which phase had more resistance for the overall mass transfer​
