Mass Transfer Relative volatility varies with the concentration of component for an ideal solution. The relative volatity of a binary mixture may be defined as the ratio of vapor pressure of component 'A' to that of component 'B', when Liquid phase obeys Dalton's law and vapor phase obeys Raoult's law Vapor phase obeys Dalton's law and liquid phase obeys Raoult's law Only vapor phase follows Raoult's law Only liquid phase obeys Dalton's law Liquid phase obeys Dalton's law and vapor phase obeys Raoult's law Vapor phase obeys Dalton's law and liquid phase obeys Raoult's law Only vapor phase follows Raoult's law Only liquid phase obeys Dalton's law ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In a packed tower, the value of HETP equals HTUOG, when the equilibrium and the operating lines are (where, HETP = height equivalant to a theoretical plate HTUOG = overall gas phase height of a transfer unit) Parallel Straight Both A & B Neither A nor B Parallel Straight Both A & B Neither A nor B ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer According to the Fenske equation, what will be the minimum number of plates required in a distillation column to separate an equimolar binary mixture of components A and B into an overhead fraction containing 99 mol% A and a bottom fraction containing 98 mol% B?
