Mass Transfer For a binary mixture with low relative volatility, continuous rectification to get pure products will require Less number of trays High reflux ratio Low reflux ratio Small cross-section column Less number of trays High reflux ratio Low reflux ratio Small cross-section column ANSWER DOWNLOAD EXAMIANS APP
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 liquid phase obeys Dalton's law Only vapor phase follows Raoult'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 liquid phase obeys Dalton's law Only vapor phase follows Raoult'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 ANSWER DOWNLOAD EXAMIANS APP
