100 mol/min of an equimolar mixture of A and B is separated in a two stage evaporation process. In the first stage, the liquid and vapor flow rates exiting the stage are each 50 mol/min. The liquid phase effluent from the first stage is fed to a second stage that operates at the same temperature as the first stage. The effluent flow rates of the liquid and vapor phases from the second stage are 25 mol/min each. The vapor phase effluent from the second stage is combined with the vapor phase effluent from the first stage. At the temperature that both stages are operating at, the vapor pressure of A is 10 kPa and the vapor pressure of B is 100 kPa. The liquid and vapor phases leaving each unit are in equilibrium. Find the composition of each stream and the pressure at each stage.
A gas mixture with a total pressure of 750 contains each of the following gases at the indicated partial pressures: , 253 ; , 120 ; and , 173 . The mixture also contains helium gas.
Under standard conditions one of the steps of glycolosis does not occur spontaneously. Can the reaction take place in the cytoplasm of a cell where the concentrations
Considering the reaction: SO2Cl2(g) --> SO2(g) +Cl2(g) Kp=2.91 and temp = 298k. the partial pressure of SO2 is 137 torr and the partial pressure of Cl2 IS 285 torr. What is partial pressure of SO2Cl2?
