Mass Transfer As the reflux ratio, in a continuous counter-current extraction is increased, the number of stages Increase Can either increase or decrease, depends on the system Remain unchanged Decrease Increase Can either increase or decrease, depends on the system Remain unchanged Decrease ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer If the solubilities of different components (in a liquid-liquid extraction system) increase with rise in temperature, then the temperature above which they dissolve completely is known as the critical solution temperature (CST or consolute temperature). If solubilities increase with decrease in temperature, then CST is the temperature below which they dissolve completely. If a binary system has no critical solution temperature, it implies that The system comprises of an azeotrope On heating, a vapor phase will appear ; while on cooling, a solid phase will appear The system comprises of partially mis-cible liquids The system comprises of miscible liquids The system comprises of an azeotrope On heating, a vapor phase will appear ; while on cooling, a solid phase will appear The system comprises of partially mis-cible liquids The system comprises of miscible liquids ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer The diffusivity (D) in a binary gas mixture is related to the pressure (P) as D ∝ P0.5 D ∝ 1/P0.5 D ∝ 1/P D ∝ 1/P1.5 D ∝ P0.5 D ∝ 1/P0.5 D ∝ 1/P D ∝ 1/P1.5 ANSWER DOWNLOAD EXAMIANS APP
