At a particular location in a counter current stripper for removal of solute A from a liquid stream, the mole fraction of solute A in the gas phase is 0.010, and the mole fraction of this species in the liquid phase is 0.035. Equilibrium distribution data at the temperature and pressure of the process are provided below:

a. If 80% of the resistance to mass-transfer is in the liquid phase, the mole fraction compositions at the gas€”liquid interface (x_A,i and y_A,i). 

b. Plot both the inter facial and bulk compositions on an x-y diagram. Given k_y = 1.0 lbmole/ft² hr, calculate the overall mass-transfer coefficient K_y for the gas phase. 

c. If the total system pressure is 2.0 atm, and the temperature is 300 K, estimate K_G and K_c.
