Please explain to me step by step.

It is desired to recover hexane vapor (solute A) from air using an absorption process. The absorption solvent is a nonvolatile mineral oil. In the dilute concentration range, the equilibrium relationship for the dissolution of hexane vapor in the mineral oil at 20C is described by p_A;i = H * x_A;i, where H= 0.15 atm. At the present conditions of operation, the hexane partial pressure in the bulk gas stream is 0.015 atm, and the dissolved hexane in the bulk absorption solvent is 5.0 mole%. The total system pressure is 1.50 atm, and the temperature is 20C. The liquid film mass-transfer coefficient k_x is 0.01 kgmole/m² s, and the gas film mass-transfer coefficient k_y is 0.02 kgmole/m² s.

a. What is the transfer rate of hexane from the gas phase to the liquid phase?
