Using the Two$-$Resistance Theory,

i$.$ show that for steady state mass transfer from a gas phase to a dilute liquid phase, the

overall mass transfer coefficient in the liquid phase, KL is related to the individual mass

transfer coefficients of the gas phase and liquid phase, kG and kL respectively, by the

following expression:
