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
Only vapor phase follows Raoult's law
Vapor phase obeys Dalton's law and liquid phase obeys Raoult's law
Only liquid phase obeys Dalton's law
Liquid phase obeys Dalton's law and vapor phase obeys Raoult's law
