A mixture of benzene and styrene is fed at a rate of 100 mol/min to a flash tank operating at 25'C. The flash produces equal flows of gas and liquid, with the liquid phase being 95% pure. Determine 1) the pressure of the flash tank, 2) the fractional recovery of benzene in the gas phase
Determine ΔSsys separately for the volume and temperature changes and show that ΔSsys=0 for a reversible adiabatic process. Also, if the expansion had instead occurred irreversibly against a constant external pressure of 1 atm
