Absolute or 100% ethanol is produced from a mixture of 95% ethanol and 5% water using the Keyes distillation process. A third component, benzene, is added to lower the volatility of the alcohol. Under these conditions, the overhead product is a constat-boiling mixture of 18.5% ethanol, 7.4% water and 74.1% benzene. Use the following data to calculate the volume of benzene that should be fed to the still in order to produce 250 litres of absolute ethanol: density of 100%...

An equilibrium mixture of PCl5(g), PCl3(g), and Cl2(g) has partial pressures of 217.0 Torr, 13.2 Torr, and 13.2 Torr, respectively. A quantity of Cl2(g) is injected into the mixture, and the total pressure jumps to 263.0 Torr (at the moment of mixing). The system then re-equilibrates. The appropriate chemical equation is PCl3(g) + Cl2(g) <---> PCl5(g) Calculate the new partial pressures after equilibrium is reestablished. P PCl3 = ? torr P PCl2 = ? torr P PCl5 = ? torr
