Question 1 : a) The mole ratio compositions of liquid and gas leaving the bottom plate of an absorption column are 0.05 and 0.60 respectively. The solute enters the column solute free. If the equilibrium relation is Y=10X (where Y is the mole ratio composition of gas in equilibrium with liquid of mole ratio composition X ) and if the Murphree plate efficiency is 50% for each plate, show that the liquid flow rate is 1.4 times the minimum liquid flow rate. b) If 85.7% of the gas entering is absorbed, what is the overall plate efficiency of the column
