Two film theory applies for absorption of a solute from a gas mixture into a liquid solvent. The interfacial mass transfer coefficient (in $mol \: m^{-2} \: s^{-1}$) for the gas side is $0.1$ and for the liquid side is $3$. The equilibrium relationship is $y^*=2x$, where $x$ and $y^*$ are mole fractions of the solute in the liquid and gas phases, respectively. The ratio of the mass transfer resistance in the liquid film to the overall resistance is

1. $0.0161$
2. $0.0322$
3. $0.0625$
4. $0.0645$
