Mass Transfer A distillation column with N plates is being operated under normal conditions. At some point of time, the operation is shifted to total reflux condition (i.e., no product and residue are being withdrawn and feed to the column is stopped). At the new steady state, Composition of vapors and that of liquid do not vary throughout the column Reboiler load and condenser load are minimum The top and bottom compositions are unchanged with and without total reflux The top and bottom compositions correspond to the maximum enrichment available Composition of vapors and that of liquid do not vary throughout the column Reboiler load and condenser load are minimum The top and bottom compositions are unchanged with and without total reflux The top and bottom compositions correspond to the maximum enrichment available ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Henry's law states that the Partial pressure of a component over a solution is proportional to the mole fraction in the vapour Partial pressure of a component over a solution is proportional to its mole fraction in the liquid Partial pressure is equal to the product of the mole fraction and total pressure Vapour pressure is equal to the product of the mole fraction and total pressure Partial pressure of a component over a solution is proportional to the mole fraction in the vapour Partial pressure of a component over a solution is proportional to its mole fraction in the liquid Partial pressure is equal to the product of the mole fraction and total pressure Vapour pressure is equal to the product of the mole fraction and total pressure ANSWER DOWNLOAD EXAMIANS APP
