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 Liquid phase obeys Dalton's law and vapor phase obeys Raoult's law Only liquid phase obeys Dalton's law Only vapor phase follows Raoult's law Vapor phase obeys Dalton's law and liquid phase obeys 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
Mass Transfer In a distillation operation, what is the effect of the temperature of the reflux stream (given below) on the condenser and reboiler loads? Reflux conditions:(i) Reflux stream is completely liquid and is at its bubble point.(ii) Reflux stream is below its bubble point. Condenser load is the same in both the cases but reboiler load is higher in case (ii) Condenser and reboiler loads are the same in both the cases Both condensor and reboiler loads are higher in case (ii) as compared to case (i) Reboiler load is the same in both the cases but condenser load is higher in case (ii) Condenser load is the same in both the cases but reboiler load is higher in case (ii) Condenser and reboiler loads are the same in both the cases Both condensor and reboiler loads are higher in case (ii) as compared to case (i) Reboiler load is the same in both the cases but condenser load is higher in case (ii) ANSWER DOWNLOAD EXAMIANS APP
