A vapor mixture of ethanol (E) and butanol (B) contains 50 mole % ethanol at 150 C and 1.0 atm. A stream of this mixture flowing at a rate of 160.0 L/s is cooled and compressed, causing some but not all of the vapor to condense (Treat this process as a single-unit operation). Liquid and vapor product streams emerge from the process in the equilibrium at T (C) and 600 mmHg. The vapor product contains 60.0 mole % ethanol. (a) Draw and label a flowchart. Perform a degree-of-freedom analysis (Gibbs phase rule). (b) Calculate the molar flow rate of feed. Just write the Raoults Law (for ethanol and butanol) by using Antoine Equation and mole balances (for ethanol and butanol). (c) Complete the calculations manually and Excel-Solver program (Show your Excel-Solver
