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 Vapor phase obeys Dalton's law and liquid phase obeys Raoult's law Only vapor phase follows Raoult's law Liquid phase obeys Dalton's law and vapor phase obeys Raoult's law Only liquid phase obeys Dalton's law Vapor phase obeys Dalton's law and liquid phase obeys Raoult's law Only vapor phase follows Raoult's law Liquid phase obeys Dalton's law and vapor phase obeys Raoult's law Only liquid phase obeys Dalton's law ANSWER DOWNLOAD EXAMIANS APP
